text: Chromosomes in the eukaryotic nucleus are highly compacted. However, for many
functional processes, including transcription initiation, the pairwise motion
of distal chromosomal elements such as enhancers and promoters is essential and
necessitates dynamic fluidity. Here, we used a live-imaging assay to simultaneously
measure the positions of pairs of enhancers and promoters and their transcriptional
output while systematically varying the genomic separation between these two DNA
loci. Our analysis reveals the coexistence of a compact globular organization
and fast subdiffusive dynamics. These combined features cause an anomalous scaling
of polymer relaxation times with genomic separation leading to long-ranged correlations.
Thus, encounter times of DNA loci are much less dependent on genomic distance
than predicted by existing polymer models, with potential consequences for eukaryotic
gene expression.

text: 'Branching morphogenesis is a ubiquitous process that gives rise to high exchange
surfaces in the vasculature and epithelial organs. Lymphatic capillaries form
branched networks, which play a key role in the circulation of tissue fluid and
immune cells. Although mouse models and correlative patient data indicate that
the lymphatic capillary density directly correlates with functional output, i.e.,
tissue fluid drainage and trafficking efficiency of dendritic cells, the mechanisms
ensuring efficient tissue coverage remain poorly understood. Here, we use the
mouse ear pinna lymphatic vessel network as a model system and combine lineage-tracing,
genetic perturbations, whole-organ reconstructions and theoretical modeling to
show that the dermal lymphatic capillaries tile space in an optimal, space-filling
manner. This coverage is achieved by two complementary mechanisms: initial tissue
invasion provides a non-optimal global scaffold via self-organized branching morphogenesis,
while VEGF-C dependent side-branching from existing capillaries rapidly optimizes
local coverage by directionally targeting low-density regions. With these two
ingredients, we show that a minimal biophysical model can reproduce quantitatively
whole-network reconstructions, across development and perturbations. Our results
show that lymphatic capillary networks can exploit local self-organizing mechanisms
to achieve tissue-scale optimization.'

text: Immune responses rely on the rapid and coordinated migration of leukocytes.
Whereas it is well established that single-cell migration is often guided by gradients
of chemokines and other chemoattractants, it remains poorly understood how these
gradients are generated, maintained, and modulated. By combining experimental
data with theory on leukocyte chemotaxis guided by the G protein–coupled receptor
(GPCR) CCR7, we demonstrate that in addition to its role as the sensory receptor
that steers migration, CCR7 also acts as a generator and a modulator of chemotactic
gradients. Upon exposure to the CCR7 ligand CCL19, dendritic cells (DCs) effectively
internalize the receptor and ligand as part of the canonical GPCR desensitization
response. We show that CCR7 internalization also acts as an effective sink for
the chemoattractant, dynamically shaping the spatiotemporal distribution of the
chemokine. This mechanism drives complex collective migration patterns, enabling
DCs to create or sharpen chemotactic gradients. We further show that these self-generated
gradients can sustain the long-range guidance of DCs, adapt collective migration
patterns to the size and geometry of the environment, and provide a guidance cue
for other comigrating cells. Such a dual role of CCR7 as a GPCR that both senses
and consumes its ligand can thus provide a novel mode of cellular self-organization.

text: Homeostatic balance in the intestinal epithelium relies on a fast cellular
turnover, which is coordinated by an intricate interplay between biochemical signalling,
mechanical forces and organ geometry. We review recent modelling approaches that
have been developed to understand different facets of this remarkable homeostatic
equilibrium. Existing models offer different, albeit complementary, perspectives
on the problem. First, biomechanical models aim to explain the local and global
mechanical stresses driving cell renewal as well as tissue shape maintenance.
Second, compartmental models provide insights into the conditions necessary to
keep a constant flow of cells with well-defined ratios of cell types, and how
perturbations can lead to an unbalance of relative compartment sizes. A third
family of models address, at the cellular level, the nature and regulation of
stem fate choices that are necessary to fuel cellular turnover. We also review
how these different approaches are starting to be integrated together across scales,
to provide quantitative predictions and new conceptual frameworks to think about
the dynamics of cell renewal in complex tissues.

text: Understanding complex living systems, which are fundamentally constrained
by physical phenomena, requires combining experimental data with theoretical physical
and mathematical models. To develop such models, collaborations between experimental
cell biologists and theoreticians are increasingly important but these two groups
often face challenges achieving mutual understanding. To help navigate these challenges,
this Perspective discusses different modelling approaches, including bottom-up
hypothesis-driven and top-down data-driven models, and highlights their strengths
and applications. Using cell mechanics as an example, we explore the integration
of specific physical models with experimental data from the molecular, cellular
and tissue level up to multiscale input. We also emphasize the importance of constraining
model complexity and outline strategies for crosstalk between experimental design
and model development. Furthermore, we highlight how physical models can provide
conceptual insights and produce unifying and generalizable frameworks for biological
phenomena. Overall, this Perspective aims to promote fruitful collaborations that
advance our understanding of complex biological systems.

text: When in equilibrium, thermal forces agitate molecules, which then diffuse,
collide and bind to form materials. However, the space of accessible structures
in which micron-scale particles can be organized by thermal forces is limited,
owing to the slow dynamics and metastable states. Active agents in a passive fluid
generate forces and flows, forming a bath with active fluctuations. Two unanswered
questions are whether those active agents can drive the assembly of passive components
into unconventional states and which material properties they will exhibit. Here
we show that passive, sticky beads immersed in a bath of swimming Escherichia
coli bacteria aggregate into unconventional clusters and gels that are controlled
by the activity of the bath. We observe a slow but persistent rotation of the
aggregates that originates in the chirality of the E. coli flagella and directs
aggregation into structures that are not accessible thermally. We elucidate the
aggregation mechanism with a numerical model of spinning, sticky beads and reproduce
quantitatively the experimental results. We show that internal activity controls
the phase diagram and the structure of the aggregates. Overall, our results highlight
the promising role of active baths in designing the structural and mechanical
properties of materials with unconventional phases.

text: The emergence of large-scale order in self-organized systems relies on local
interactions between individual components. During bacterial cell division, FtsZ—a
prokaryotic homologue of the eukaryotic protein tubulin—polymerizes into treadmilling
filaments that further organize into a cytoskeletal ring. In vitro, FtsZ filaments
can form dynamic chiral assemblies. However, how the active and passive properties
of individual filaments relate to these large-scale self-organized structures
remains poorly understood. Here we connect single-filament properties with the
mesoscopic scale by combining minimal active matter simulations and biochemical
reconstitution experiments. We show that the density and flexibility of active
chiral filaments define their global order. At intermediate densities, curved,
flexible filaments organize into chiral rings and polar bands. An effectively
nematic organization dominates for high densities and for straight, mutant filaments
with increased rigidity. Our predicted phase diagram quantitatively captures these
features, demonstrating how the flexibility, density and chirality of the active
filaments affect their collective behaviour. Our findings shed light on the fundamental
properties of active chiral matter and explain how treadmilling FtsZ filaments
organize during bacterial cell division.

text: 'Lymph nodes (LNs) comprise two main structural elements: fibroblastic reticular
cells that form dedicated niches for immune cell interaction and capsular fibroblasts
that build a shell around the organ. Immunological challenge causes LNs to increase
more than tenfold in size within a few days. Here, we characterized the biomechanics
of LN swelling on the cellular and organ scale. We identified lymphocyte trapping
by influx and proliferation as drivers of an outward pressure force, causing fibroblastic
reticular cells of the T-zone (TRCs) and their associated conduits to stretch.
After an initial phase of relaxation, TRCs sensed the resulting strain through
cell matrix adhesions, which coordinated local growth and remodeling of the stromal
network. While the expanded TRC network readopted its typical configuration, a
massive fibrotic reaction of the organ capsule set in and countered further organ
expansion. Thus, different fibroblast populations mechanically control LN swelling
in a multitier fashion.'

text: "Cell dispersion from a confined area is fundamental in a number of biological
processes,\r\nincluding cancer metastasis. To date, a quantitative understanding
of the interplay of single\r\ncell motility, cell proliferation, and intercellular
contacts remains elusive. In particular, the role\r\nof E- and N-Cadherin junctions,
central components of intercellular contacts, is still\r\ncontroversial. Combining
theoretical modeling with in vitro observations, we investigate the\r\ncollective
spreading behavior of colonies of human cancer cells (T24). The spreading of these\r\ncolonies
is driven by stochastic single-cell migration with frequent transient cell-cell
contacts.\r\nWe find that inhibition of E- and N-Cadherin junctions decreases
colony spreading and average\r\nspreading velocities, without affecting the strength
of correlations in spreading velocities of\r\nneighboring cells. Based on a biophysical
simulation model for cell migration, we show that the\r\nbehavioral changes upon
disruption of these junctions can be explained by reduced repulsive\r\nexcluded
volume interactions between cells. This suggests that in cancer cell migration,\r\ncadherin-based
intercellular contacts sharpen cell boundaries leading to repulsive rather than\r\ncohesive
interactions between cells, thereby promoting efficient cell spreading during
collective\r\nmigration.\r\n"

text: Although rigidity and jamming transitions have been widely studied in physics
and material science, their importance in a number of biological processes, including
embryo development, tissue homeostasis, wound healing, and disease progression,
has only begun to be recognized in the past few years. The hypothesis that biological
systems can undergo rigidity/jamming transitions is attractive, as it would allow
these systems to change their material properties rapidly and strongly. However,
whether such transitions indeed occur in biological systems, how they are being
regulated, and what their physiological relevance might be, is still being debated.
Here, we review theoretical and experimental advances from the past few years,
focusing on the regulation and role of potential tissue rigidity transitions in
different biological processes.

text: In development, lineage segregation is coordinated in time and space. An important
example is the mammalian inner cell mass, in which the primitive endoderm (PrE,
founder of the yolk sac) physically segregates from the epiblast (EPI, founder
of the fetus). While the molecular requirements have been well studied, the physical
mechanisms determining spatial segregation between EPI and PrE remain elusive.
Here, we investigate the mechanical basis of EPI and PrE sorting. We find that
rather than the differences in static cell surface mechanical parameters as in
classical sorting models, it is the differences in surface fluctuations that robustly
ensure physical lineage sorting. These differential surface fluctuations systematically
correlate with differential cellular fluidity, which we propose together constitute
a non-equilibrium sorting mechanism for EPI and PrE lineages. By combining experiments
and modeling, we identify cell surface dynamics as a key factor orchestrating
the correct spatial segregation of the founder embryonic lineages.

text: Embryo development requires biochemical signalling to generate patterns of
cell fates and active mechanical forces to drive tissue shape changes. However,
how these processes are coordinated, and how tissue patterning is preserved despite
the cellular flows occurring during morphogenesis, remains poorly understood.
Gastrulation is a crucial embryonic stage that involves both patterning and internalization
of the mesendoderm germ layer tissue. Here we show that, in zebrafish embryos,
a gradient in Nodal signalling orchestrates pattern-preserving internalization
movements by triggering a motility-driven unjamming transition. In addition to
its role as a morphogen determining embryo patterning, graded Nodal signalling
mechanically subdivides the mesendoderm into a small fraction of highly protrusive
leader cells, able to autonomously internalize via local unjamming, and less protrusive
followers, which need to be pulled inwards by the leaders. The Nodal gradient
further enforces a code of preferential adhesion coupling leaders to their immediate
followers, resulting in a collective and ordered mode of internalization that
preserves mesendoderm patterning. Integrating this dual mechanical role of Nodal
signalling into minimal active particle simulations quantitatively predicts both
physiological and experimentally perturbed internalization movements. This provides
a quantitative framework for how a morphogen-encoded unjamming transition can
bidirectionally couple tissue mechanics with patterning during complex three-dimensional
morphogenesis.

text: The development dynamics and self-organization of glandular branched epithelia
is of utmost importance for our understanding of diverse processes ranging from
normal tissue growth to the growth of cancerous tissues. Using single primary
murine pancreatic ductal adenocarcinoma (PDAC) cells embedded in a collagen matrix
and adapted media supplementation, we generate organoids that self-organize into
highly branched structures displaying a seamless lumen connecting terminal end
buds, replicating in vivo PDAC architecture. We identify distinct morphogenesis
phases, each characterized by a unique pattern of cell invasion, matrix deformation,
protein expression, and respective molecular dependencies. We propose a minimal
theoretical model of a branching and proliferating tissue, capturing the dynamics
of the first phases. Observing the interaction of morphogenesis, mechanical environment
and gene expression in vitro sets a benchmark for the understanding of self-organization
processes governing complex organoid structure formation processes and branching
morphogenesis.

text: The sculpting of germ layers during gastrulation relies on the coordinated
migration of progenitor cells, yet the cues controlling these long-range directed
movements remain largely unknown. While directional migration often relies on
a chemokine gradient generated from a localized source, we find that zebrafish
ventrolateral mesoderm is guided by a self-generated gradient of the initially
uniformly expressed and secreted protein Toddler/ELABELA/Apela. We show that the
Apelin receptor, which is specifically expressed in mesodermal cells, has a dual
role during gastrulation, acting as a scavenger receptor to generate a Toddler
gradient, and as a chemokine receptor to sense this guidance cue. Thus, we uncover
a single receptor–based self-generated gradient as the enigmatic guidance cue
that can robustly steer the directional migration of mesoderm through the complex
and continuously changing environment of the gastrulating embryo.

text: Cell migration in confining physiological environments relies on the concerted
dynamics of several cellular components, including protrusions, adhesions with
the environment, and the cell nucleus. However, it remains poorly understood how
the dynamic interplay of these components and the cell polarity determine the
emergent migration behavior at the cellular scale. Here, we combine data-driven
inference with a mechanistic bottom-up approach to develop a model for protrusion
and polarity dynamics in confined cell migration, revealing how the cellular dynamics
adapt to confining geometries. Specifically, we use experimental data of joint
protrusion-nucleus migration trajectories of cells on confining micropatterns
to systematically determine a mechanistic model linking the stochastic dynamics
of cell polarity, protrusions, and nucleus. This model indicates that the cellular
dynamics adapt to confining constrictions through a switch in the polarity dynamics
from a negative to a positive self-reinforcing feedback loop. Our model further
reveals how this feedback loop leads to stereotypical cycles of protrusion-nucleus
dynamics that drive the migration of the cell through constrictions. These cycles
are disrupted upon perturbation of cytoskeletal components, indicating that the
positive feedback is controlled by cellular migration mechanisms. Our data-driven
theoretical approach therefore identifies polarity feedback adaptation as a key
mechanism in confined cell migration.

text: The morphology and functionality of the epithelial lining differ along the
intestinal tract, but tissue renewal at all sites is driven by stem cells at the
base of crypts1,2,3. Whether stem cell numbers and behaviour vary at different
sites is unknown. Here we show using intravital microscopy that, despite similarities
in the number and distribution of proliferative cells with an Lgr5 signature in
mice, small intestinal crypts contain twice as many effective stem cells as large
intestinal crypts. We find that, although passively displaced by a conveyor-belt-like
upward movement, small intestinal cells positioned away from the crypt base can
function as long-term effective stem cells owing to Wnt-dependent retrograde cellular
movement. By contrast, the near absence of retrograde movement in the large intestine
restricts cell repositioning, leading to a reduction in effective stem cell number.
Moreover, after suppression of the retrograde movement in the small intestine,
the number of effective stem cells is reduced, and the rate of monoclonal conversion
of crypts is accelerated. Together, these results show that the number of effective
stem cells is determined by active retrograde movement, revealing a new channel
of stem cell regulation that can be experimentally and pharmacologically manipulated.

text: Collective cell migration offers a rich field of study for non-equilibrium
physics and cellular biology, revealing phenomena such as glassy dynamics, pattern
formation and active turbulence. However, how mechanical and chemical signalling
are integrated at the cellular level to give rise to such collective behaviours
remains unclear. We address this by focusing on the highly conserved phenomenon
of spatiotemporal waves of density and extracellular signal-regulated kinase (ERK)
activation, which appear both in vitro and in vivo during collective cell migration
and wound healing. First, we propose a biophysical theory, backed by mechanical
and optogenetic perturbation experiments, showing that patterns can be quantitatively
explained by a mechanochemical coupling between active cellular tensions and the
mechanosensitive ERK pathway. Next, we demonstrate how this biophysical mechanism
can robustly induce long-ranged order and migration in a desired orientation,
and we determine the theoretically optimal wavelength and period for inducing
maximal migration towards free edges, which fits well with experimentally observed
dynamics. We thereby provide a bridge between the biophysical origin of spatiotemporal
instabilities and the design principles of robust and efficient long-ranged migration.

text: 'Organ function depends on tissues adopting the correct architecture. However,
insights into organ architecture are currently hampered by an absence of standardized
quantitative 3D analysis. We aimed to develop a robust technology to visualize,
digitalize, and segment the architecture of two tubular systems in 3D: double
resin casting micro computed tomography (DUCT). As proof of principle, we applied
DUCT to a mouse model for Alagille syndrome (Jag1Ndr/Ndr mice), characterized
by intrahepatic bile duct paucity, that can spontaneously generate a biliary system
in adulthood. DUCT identified increased central biliary branching and peripheral
bile duct tortuosity as two compensatory processes occurring in distinct regions
of Jag1Ndr/Ndr liver, leading to full reconstitution of wild-type biliary volume
and phenotypic recovery. DUCT is thus a powerful new technology for 3D analysis,
which can reveal novel phenotypes and provide a standardized method of defining
liver architecture in mouse models.'

text: Assemblies of actin and its regulators underlie the dynamic morphology of
all eukaryotic cells. To understand how actin regulatory proteins work together
to generate actin-rich structures such as filopodia, we analyzed the localization
of diverse actin regulators within filopodia in Drosophila embryos and in a complementary
in vitro system of filopodia-like structures (FLSs). We found that the composition
of the regulatory protein complex where actin is incorporated (the filopodial
tip complex) is remarkably heterogeneous both in vivo and in vitro. Our data reveal
that different pairs of proteins correlate with each other and with actin bundle
length, suggesting the presence of functional subcomplexes. This is consistent
with a theoretical framework where three or more redundant subcomplexes join the
tip complex stochastically, with any two being sufficient to drive filopodia formation.
We provide an explanation for the observed heterogeneity and suggest that a mechanism
based on multiple components allows stereotypical filopodial dynamics to arise
from diverse upstream signaling pathways.

text: Embryo morphogenesis is impacted by dynamic changes in tissue material properties,
which have been proposed to occur via processes akin to phase transitions (PTs).
Here, we show that rigidity percolation provides a simple and robust theoretical
framework to predict material/structural PTs of embryonic tissues from local cell
connectivity. By using percolation theory, combined with directly monitoring dynamic
changes in tissue rheology and cell contact mechanics, we demonstrate that the
zebrafish blastoderm undergoes a genuine rigidity PT, brought about by a small
reduction in adhesion-dependent cell connectivity below a critical value. We quantitatively
predict and experimentally verify hallmarks of PTs, including power-law exponents
and associated discontinuities of macroscopic observables. Finally, we show that
this uniform PT depends on blastoderm cells undergoing meta-synchronous divisions
causing random and, consequently, uniform changes in cell connectivity. Collectively,
our theoretical and experimental findings reveal the structural basis of material
PTs in an organismal context.

text: 'The way in which interactions between mechanics and biochemistry lead to
the emergence of complex cell and tissue organization is an old question that
has recently attracted renewed interest from biologists, physicists, mathematicians
and computer scientists. Rapid advances in optical physics, microscopy and computational
image analysis have greatly enhanced our ability to observe and quantify spatiotemporal
patterns of signalling, force generation, deformation, and flow in living cells
and tissues. Powerful new tools for genetic, biophysical and optogenetic manipulation
are allowing us to perturb the underlying machinery that generates these patterns
in increasingly sophisticated ways. Rapid advances in theory and computing have
made it possible to construct predictive models that describe how cell and tissue
organization and dynamics emerge from the local coupling of biochemistry and mechanics.
Together, these advances have opened up a wealth of new opportunities to explore
how mechanochemical patterning shapes organismal development. In this roadmap,
we present a series of forward-looking case studies on mechanochemical patterning
in development, written by scientists working at the interface between the physical
and biological sciences, and covering a wide range of spatial and temporal scales,
organisms, and modes of development. Together, these contributions highlight the
many ways in which the dynamic coupling of mechanics and biochemistry shapes biological
dynamics: from mechanoenzymes that sense force to tune their activity and motor
output, to collectives of cells in tissues that flow and redistribute biochemical
signals during development.'

text: Intestinal organoids derived from single cells undergo complex crypt–villus
patterning and morphogenesis. However, the nature and coordination of the underlying
forces remains poorly characterized. Here, using light-sheet microscopy and large-scale
imaging quantification, we demonstrate that crypt formation coincides with a stark
reduction in lumen volume. We develop a 3D biophysical model to computationally
screen different mechanical scenarios of crypt morphogenesis. Combining this with
live-imaging data and multiple mechanical perturbations, we show that actomyosin-driven
crypt apical contraction and villus basal tension work synergistically with lumen
volume reduction to drive crypt morphogenesis, and demonstrate the existence of
a critical point in differential tensions above which crypt morphology becomes
robust to volume changes. Finally, we identified a sodium/glucose cotransporter
that is specific to differentiated enterocytes that modulates lumen volume reduction
through cell swelling in the villus region. Together, our study uncovers the cellular
basis of how cell fate modulates osmotic and actomyosin forces to coordinate robust
morphogenesis.

text: Proper control of division orientation and symmetry, largely determined by
spindle positioning, is essential to development and homeostasis. Spindle positioning
has been extensively studied in cells dividing in two-dimensional (2D) environments
and in epithelial tissues, where proteins such as NuMA (also known as NUMA1) orient
division along the interphase long axis of the cell. However, little is known
about how cells control spindle positioning in three-dimensional (3D) environments,
such as early mammalian embryos and a variety of adult tissues. Here, we use mouse
embryonic stem cells (ESCs), which grow in 3D colonies, as a model to investigate
division in 3D. We observe that, at the periphery of 3D colonies, ESCs display
high spindle mobility and divide asymmetrically. Our data suggest that enhanced
spindle movements are due to unequal distribution of the cell–cell junction protein
E-cadherin between future daughter cells. Interestingly, when cells progress towards
differentiation, division becomes more symmetric, with more elongated shapes in
metaphase and enhanced cortical NuMA recruitment in anaphase. Altogether, this
study suggests that in 3D contexts, the geometry of the cell and its contacts
with neighbors control division orientation and symmetry.

text: In dense biological tissues, cell types performing different roles remain
segregated by maintaining sharp interfaces. To better understand the mechanisms
for such sharp compartmentalization, we study the effect of an imposed heterotypic
tension at the interface between two distinct cell types in a fully 3D Voronoi
model for confluent tissues. We find that cells rapidly sort and self-organize
to generate a tissue-scale interface between cell types, and cells adjacent to
this interface exhibit signature geometric features including nematic-like ordering,
bimodal facet areas, and registration, or alignment, of cell centers on either
side of the two-tissue interface. The magnitude of these features scales directly
with the magnitude of the imposed tension, suggesting that biologists can estimate
the magnitude of tissue surface tension between two tissue types simply by segmenting
a 3D tissue. To uncover the underlying physical mechanisms driving these geometric
features, we develop two minimal, ordered models using two different underlying
lattices that identify an energetic competition between bulk cell shapes and tissue
interface area. When the interface area dominates, changes to neighbor topology
are costly and occur less frequently, which generates the observed geometric features.

text: Branching morphogenesis governs the formation of many organs such as lung,
kidney, and the neurovascular system. Many studies have explored system-specific
molecular and cellular regulatory mechanisms, as well as self-organizing rules
underlying branching morphogenesis. However, in addition to local cues, branched
tissue growth can also be influenced by global guidance. Here, we develop a theoretical
framework for a stochastic self-organized branching process in the presence of
external cues. Combining analytical theory with numerical simulations, we predict
differential signatures of global vs. local regulatory mechanisms on the branching
pattern, such as angle distributions, domain size, and space-filling efficiency.
We find that branch alignment follows a generic scaling law determined by the
strength of global guidance, while local interactions influence the tissue density
but not its overall territory. Finally, using zebrafish innervation as a model
system, we test these key features of the model experimentally. Our work thus
provides quantitative predictions to disentangle the role of different types of
cues in shaping branched structures across scales.

text: How tissues acquire complex shapes is a fundamental question in biology and
regenerative medicine. Zebrafish semicircular canals form from invaginations in
the otic epithelium (buds) that extend and fuse to form the hubs of each canal.
We find that conventional actomyosin-driven behaviors are not required. Instead,
local secretion of hyaluronan, made by the enzymes uridine 5′-diphosphate dehydrogenase
(ugdh) and hyaluronan synthase 3 (has3), drives canal morphogenesis. Charged hyaluronate
polymers osmotically swell with water and generate isotropic extracellular pressure
to deform the overlying epithelium into buds. The mechanical anisotropy needed
to shape buds into tubes is conferred by a polarized distribution of actomyosin
and E-cadherin-rich membrane tethers, which we term cytocinches. Most work on
tissue morphogenesis ascribes actomyosin contractility as the driving force, while
the extracellular matrix shapes tissues through differential stiffness. Our work
inverts this expectation. Hyaluronate pressure shaped by anisotropic tissue stiffness
may be a widespread mechanism for powering morphological change in organogenesis
and tissue engineering.

text: The early development of many organisms involves the folding of cell monolayers,
but this behaviour is difficult to reproduce in vitro; therefore, both mechanistic
causes and effects of local curvature remain unclear. Here we study epithelial
cell monolayers on corrugated hydrogels engineered into wavy patterns, examining
how concave and convex curvatures affect cellular and nuclear shape. We find that
substrate curvature affects monolayer thickness, which is larger in valleys than
crests. We show that this feature generically arises in a vertex model, leading
to the hypothesis that cells may sense curvature by modifying the thickness of
the tissue. We find that local curvature also affects nuclear morphology and positioning,
which we explain by extending the vertex model to take into account membrane–nucleus
interactions, encoding thickness modulation in changes to nuclear deformation
and position. We propose that curvature governs the spatial distribution of yes-associated
proteins via nuclear shape and density changes. We show that curvature also induces
significant variations in lamins, chromatin condensation and cell proliferation
rate in folded epithelial tissues. Together, this work identifies active cell
mechanics and nuclear mechanoadaptation as the key players of the mechanistic
regulation of epithelia to substrate curvature.

text: In the living cell, we encounter a large variety of motile processes such
as organelle transport and cytoskeleton remodeling. These processes are driven
by motor proteins that generate force by transducing chemical free energy into
mechanical work. In many cases, the molecular motors work in teams to collectively
generate larger forces. Recent optical trapping experiments on small teams of
cytoskeletal motors indicated that the collectively generated force increases
with the size of the motor team but that this increase depends on the motor type
and on whether the motors are studied in vitro or in vivo. Here, we use the theory
of stochastic processes to describe the motion of N motors in a stationary optical
trap and to compute the N-dependence of the collectively generated forces. We
consider six distinct motor types, two kinesins, two dyneins, and two myosins.
We show that the force increases always linearly with N but with a prefactor that
depends on the performance of the single motor. Surprisingly, this prefactor increases
for weaker motors with a lower stall force. This counter-intuitive behavior reflects
the increased probability with which stronger motors detach from the filament
during strain generation. Our theoretical results are in quantitative agreement
with experimental data on small teams of kinesin-1 motors.

text: 'In many real-world systems, information can be transmitted in two qualitatively
different ways: by copying or by transformation. Copying occurs when messages
are transmitted without modification, e.g. when an offspring receives an unaltered
copy of a gene from its parent. Transformation occurs when messages are modified
systematically during transmission, e.g. when mutational biases occur during genetic
replication. Standard information-theoretic measures do not distinguish these
two modes of information transfer, although they may reflect different mechanisms
and have different functional consequences. Starting from a few simple axioms,
we derive a decomposition of mutual information into the information transmitted
by copying versus the information transmitted by transformation. We begin with
a decomposition that applies when the source and destination of the channel have
the same set of messages and a notion of message identity exists. We then generalize
our decomposition to other kinds of channels, which can involve different source
and destination sets and broader notions of similarity. In addition, we show that
copy information can be interpreted as the minimal work needed by a physical copying
process, which is relevant for understanding the physics of replication. We use
the proposed decomposition to explore a model of amino acid substitution rates.
Our results apply to any system in which the fidelity of copying, rather than
simple predictability, is of critical relevance.'

text: During embryonic and postnatal development, organs and tissues grow steadily
to achieve their final size at the end of puberty. However, little is known about
the cellular dynamics that mediate postnatal growth. By combining in vivo clonal
lineage tracing, proliferation kinetics, single-cell transcriptomics, andin vitro
micro-pattern experiments, we resolved the cellular dynamics taking place during
postnatal skin epidermis expansion. Our data revealed that harmonious growth is
engineered by a single population of developmental progenitors presenting a fixed
fate imbalance of self-renewing divisions with an ever-decreasing proliferation
rate. Single-cell RNA sequencing revealed that epidermal developmental progenitors
form a more uniform population compared with adult stem and progenitor cells.
Finally, we found that the spatial pattern of cell division orientation is dictated
locally by the underlying collagen fiber orientation. Our results uncover a simple
design principle of organ growth where progenitors and differentiated cells expand
in harmony with their surrounding tissues.

text: Understanding to what extent stem cell potential is a cell-intrinsic property
or an emergent behavior coming from global tissue dynamics and geometry is a key
outstanding question of systems and stem cell biology. Here, we propose a theory
of stem cell dynamics as a stochastic competition for access to a spatially localized
niche, giving rise to a stochastic conveyor-belt model. Cell divisions produce
a steady cellular stream which advects cells away from the niche, while random
rearrangements enable cells away from the niche to be favorably repositioned.
Importantly, even when assuming that all cells in a tissue are molecularly equivalent,
we predict a common (“universal”) functional dependence of the long-term clonal
survival probability on distance from the niche, as well as the emergence of a
well-defined number of functional stem cells, dependent only on the rate of random
movements vs. mitosis-driven advection. We test the predictions of this theory
on datasets of pubertal mammary gland tips and embryonic kidney tips, as well
as homeostatic intestinal crypts. Importantly, we find good agreement for the
predicted functional dependency of the competition as a function of position,
and thus functional stem cell number in each organ. This argues for a key role
of positional fluctuations in dictating stem cell number and dynamics, and we
discuss the applicability of this theory to other settings.

text: Pancreatic islets play an essential role in regulating blood glucose level.
Although the molecular pathways underlying islet cell differentiation are beginning
to be resolved, the cellular basis of islet morphogenesis and fate allocation
remain unclear. By combining unbiased and targeted lineage tracing, we address
the events leading to islet formation in the mouse. From the statistical analysis
of clones induced at multiple embryonic timepoints, here we show that, during
the secondary transition, islet formation involves the aggregation of multiple
equipotent endocrine progenitors that transition from a phase of stochastic amplification
by cell division into a phase of sublineage restriction and limited islet fission.
Together, these results explain quantitatively the heterogeneous size distribution
and degree of polyclonality of maturing islets, as well as dispersion of progenitors
within and between islets. Further, our results show that, during the secondary
transition, α- and β-cells are generated in a contemporary manner. Together, these
findings provide insight into the cellular basis of islet development.

text: Cell fate transitions are key to development and homeostasis. It is thus essential
to understand the cellular mechanisms controlling fate transitions. Cell division
has been implicated in fate decisions in many stem cell types, including neuronal
and epithelial progenitors. In other stem cells, such as embryonic stem (ES) cells,
the role of division remains unclear. Here, we show that exit from naive pluripotency
in mouse ES cells generally occurs after a division. We further show that exit
timing is strongly correlated between sister cells, which remain connected by
cytoplasmic bridges long after division, and that bridge abscission progressively
accelerates as cells exit naive pluripotency. Finally, interfering with abscission
impairs naive pluripotency exit, and artificially inducing abscission accelerates
it. Altogether, our data indicate that a switch in the division machinery leading
to faster abscission regulates pluripotency exit. Our study identifies abscission
as a key cellular process coupling cell division to fate transitions.

text: Understanding the thermodynamics of the duplication process is a fundamental
step towards a comprehensive physical theory of biological systems. However, the
immense complexity of real cells obscures the fundamental tensions between energy
gradients and entropic contributions that underlie duplication. The study of synthetic,
feasible systems reproducing part of the key ingredients of living entities but
overcoming major sources of biological complexity is of great relevance to deepen
the comprehension of the fundamental thermodynamic processes underlying life and
its prevalence. In this paper an abstract—yet realistic—synthetic system made
of small synthetic protocell aggregates is studied in detail. A fundamental relation
between free energy and entropic gradients is derived for a general, non-equilibrium
scenario, setting the thermodynamic conditions for the occurrence and prevalence
of duplication phenomena. This relation sets explicitly how the energy gradients
invested in creating and maintaining structural—and eventually, functional—elements
of the system must always compensate the entropic gradients, whose contributions
come from changes in the translational, configurational, and macrostate entropies,
as well as from dissipation due to irreversible transitions. Work/energy relations
are also derived, defining lower bounds on the energy required for the duplication
event to take place. A specific example including real ternary emulsions is provided
in order to grasp the orders of magnitude involved in the problem. It is found
that the minimal work invested over the system to trigger a duplication event
is around ~ 10−13J , which results, in the case of duplication of all the vesicles
contained in a liter of emulsion, in an amount of energy around ~ 1kJ . Without
aiming to describe a truly biological process of duplication, this theoretical
contribution seeks to explicitly define and identify the key actors that participate
in it.

text: The formation of self-organized patterns is key to the morphogenesis of multicellular
organisms, although a comprehensive theory of biological pattern formation is
still lacking. Here, we propose a minimal model combining tissue mechanics with
morphogen turnover and transport to explore routes to patterning. Our active description
couples morphogen reaction and diffusion, which impact cell differentiation and
tissue mechanics, to a two-phase poroelastic rheology, where one tissue phase
consists of a poroelastic cell network and the other one of a permeating extracellular
fluid, which provides a feedback by actively transporting morphogens. While this
model encompasses previous theories approximating tissues to inert monophasic
media, such as Turing’s reaction–diffusion model, it overcomes some of their key
limitations permitting pattern formation via any two-species biochemical kinetics
due to mechanically induced cross-diffusion flows. Moreover, we describe a qualitatively
different advection-driven Keller–Segel instability which allows for the formation
of patterns with a single morphogen and whose fundamental mode pattern robustly
scales with tissue size. We discuss the potential relevance of these findings
for tissue morphogenesis.

text: Adult intestinal stem cells are located at the bottom of crypts of Lieberkühn,
where they express markers such as LGR5 1,2 and fuel the constant replenishment
of the intestinal epithelium1. Although fetal LGR5-expressing cells can give rise
to adult intestinal stem cells3,4, it remains unclear whether this population
in the patterned epithelium represents unique intestinal stem-cell precursors.
Here we show, using unbiased quantitative lineage-tracing approaches, biophysical
modelling and intestinal transplantation, that all cells of the mouse intestinal
epithelium—irrespective of their location and pattern of LGR5 expression in the
fetal gut tube—contribute actively to the adult intestinal stem cell pool. Using
3D imaging, we find that during fetal development the villus undergoes gross remodelling
and fission. This brings epithelial cells from the non-proliferative villus into
the proliferative intervillus region, which enables them to contribute to the
adult stem-cell niche. Our results demonstrate that large-scale remodelling of
the intestinal wall and cell-fate specification are closely linked. Moreover,
these findings provide a direct link between the observed plasticity and cellular
reprogramming of differentiating cells in adult tissues following damage5,6,7,8,9,
revealing that stem-cell identity is an induced rather than a hardwired property.

text: Branching morphogenesis is a prototypical example of complex three-dimensional
organ sculpting, required in multiple developmental settings to maximize the area
of exchange surfaces. It requires, in particular, the coordinated growth of different
cell types together with complex patterning to lead to robust macroscopic outputs.
In recent years, novel multiscale quantitative biology approaches, together with
biophysical modelling, have begun to shed new light of this topic. Here, we wish
to review some of these recent developments, highlighting the generic design principles
that can be abstracted across different branched organs, as well as the implications
for the broader fields of stem cell, developmental and systems biology.

text: There is increasing evidence that both mechanical and biochemical signals
play important roles in development and disease. The development of complex organisms,
in particular, has been proposed to rely on the feedback between mechanical and
biochemical patterning events. This feedback occurs at the molecular level via
mechanosensation but can also arise as an emergent property of the system at the
cellular and tissue level. In recent years, dynamic changes in tissue geometry,
flow, rheology, and cell fate specification have emerged as key platforms of mechanochemical
feedback loops in multiple processes. Here, we review recent experimental and
theoretical advances in understanding how these feedbacks function in development
and disease.

text: Steady-state turnover is a hallmark of epithelial tissues throughout adult
life. Intestinal epithelial turnover is marked by continuous cell migration, which
is assumed to be driven by mitotic pressure from the crypts. However, the balance
of forces in renewal remains ill-defined. Combining biophysical modeling and quantitative
three-dimensional tissue imaging with genetic and physical manipulations, we revealed
the existence of an actin-related protein 2/3 complex–dependent active migratory
force, which explains quantitatively the profiles of cell speed, density, and
tissue tension along the villi. Cells migrate collectively with minimal rearrangements
while displaying dual—apicobasal and front-back—polarity characterized by actin-rich
basal protrusions oriented in the direction of migration. We propose that active
migration is a critical component of gut epithelial turnover.

text: Tissue morphogenesis is driven by mechanical forces that elicit changes in
cell size, shape and motion. The extent by which forces deform tissues critically
depends on the rheological properties of the recipient tissue. Yet, whether and
how dynamic changes in tissue rheology affect tissue morphogenesis and how they
are regulated within the developing organism remain unclear. Here, we show that
blastoderm spreading at the onset of zebrafish morphogenesis relies on a rapid,
pronounced and spatially patterned tissue fluidization. Blastoderm fluidization
is temporally controlled by mitotic cell rounding-dependent cell–cell contact
disassembly during the last rounds of cell cleavages. Moreover, fluidization is
spatially restricted to the central blastoderm by local activation of non-canonical
Wnt signalling within the blastoderm margin, increasing cell cohesion and thereby
counteracting the effect of mitotic rounding on contact disassembly. Overall,
our results identify a fluidity transition mediated by loss of cell cohesion as
a critical regulator of embryo morphogenesis.

text: Segregation of maternal determinants within the oocyte constitutes the first
step in embryo patterning. In zebrafish oocytes, extensive ooplasmic streaming
leads to the segregation of ooplasm from yolk granules along the animal-vegetal
axis of the oocyte. Here, we show that this process does not rely on cortical
actin reorganization, as previously thought, but instead on a cell-cycle-dependent
bulk actin polymerization wave traveling from the animal to the vegetal pole of
the oocyte. This wave functions in segregation by both pulling ooplasm animally
and pushing yolk granules vegetally. Using biophysical experimentation and theory,
we show that ooplasm pulling is mediated by bulk actin network flows exerting
friction forces on the ooplasm, while yolk granule pushing is achieved by a mechanism
closely resembling actin comet formation on yolk granules. Our study defines a
novel role of cell-cycle-controlled bulk actin polymerization waves in oocyte
polarization via ooplasmic segregation.

text: The actomyosin cytoskeleton, a key stress-producing unit in epithelial cells,
oscillates spontaneously in a wide variety of systems. Although much of the signal
cascade regulating myosin activity has been characterized, the origin of such
oscillatory behavior is still unclear. Here, we show that basal myosin II oscillation
in Drosophila ovarian epithelium is not controlled by actomyosin cortical tension,
but instead relies on a biochemical oscillator involving ROCK and myosin phosphatase.
Key to this oscillation is a diffusive ROCK flow, linking junctional Rho1 to medial
actomyosin cortex, and dynamically maintained by a self-activation loop reliant
on ROCK kinase activity. In response to the resulting myosin II recruitment, myosin
phosphatase is locally enriched and shuts off ROCK and myosin II signals. Coupling
Drosophila genetics, live imaging, modeling, and optogenetics, we uncover an intrinsic
biochemical oscillator at the core of myosin II regulatory network, shedding light
on the spatio-temporal dynamics of force generation.

text: Recent lineage tracing studies have revealed that mammary gland homeostasis
relies on unipotent stem cells. However, whether and when lineage restriction
occurs during embryonic mammary development, and which signals orchestrate cell
fate specification, remain unknown. Using a combination of in vivo clonal analysis
with whole mount immunofluorescence and mathematical modelling of clonal dynamics,
we found that embryonic multipotent mammary cells become lineage-restricted surprisingly
early in development, with evidence for unipotency as early as E12.5 and no statistically
discernable bipotency after E15.5. To gain insights into the mechanisms governing
the switch from multipotency to unipotency, we used gain-of-function Notch1 mice
and demonstrated that Notch activation cell autonomously dictates luminal cell
fate specification to both embryonic and basally committed mammary cells. These
functional studies have important implications for understanding the signals underlying
cell plasticity and serve to clarify how reactivation of embryonic programs in
adult cells can lead to cancer.

text: Pancreas development involves a coordinated process in which an early phase
of cell segregation is followed by a longer phase of lineage restriction, expansion,
and tissue remodeling. By combining clonal tracing and whole-mount reconstruction
with proliferation kinetics and single-cell transcriptional profiling, we define
the functional basis of pancreas morphogenesis. We show that the large-scale organization
of mouse pancreas can be traced to the activity of self-renewing precursors positioned
at the termini of growing ducts, which act collectively to drive serial rounds
of stochastic ductal bifurcation balanced by termination. During this phase of
branching morphogenesis, multipotent precursors become progressively fate-restricted,
giving rise to self-renewing acinar-committed precursors that are conveyed with
growing ducts, as well as ductal progenitors that expand the trailing ducts and
give rise to delaminating endocrine cells. These findings define quantitatively
how the functional behavior and lineage progression of precursor pools determine
the large-scale patterning of pancreatic sub-compartments.

text: "Branching morphogenesis remains a subject of abiding interest. Although
\ much is \r\nknown about the gene regulatory programs and signaling pathways
that operate at \r\nthe cellular scale, it has remained unclear how the macroscopic
features of branched \r\norgans, including their size, network topology and
\ spatial patterning, are encoded. \r\nLately, it has been proposed that,
these features can be explained quantitatively in \r\nseveral organs within a
single unifying framework. Based on large-\r\nscale organ recon\r\n-\r\nstructions
\ and cell lineage tracing, it has been argued that morphogenesis follows
\ \r\nfrom the collective dynamics of sublineage- \r\nrestricted self- \r\nrenewing
progenitor cells, \r\nlocalized at ductal tips, that act cooperatively to drive
a serial process of ductal elon\r\n-\r\ngation and stochastic tip bifurcation.
By correlating differentiation or cell cycle exit \r\nwith proximity to maturing
ducts, this dynamic results in the specification of a com-\r\nplex network of
\ defined density and statistical organization. These results suggest \r\nthat,
for several mammalian tissues, branched epithelial structures develop as a self-
\r\norganized process, reliant upon a strikingly simple, but generic,
\ set of local rules, \r\nwithout recourse to a rigid and deterministic
\ sequence of genetically programmed \r\nevents. Here, we review the basis
of these findings and discuss their implications."

text: Cell shape is determined by a balance of intrinsic properties of the cell
as well as its mechanochemical environment. Inhomogeneous shape changes underlie
many morphogenetic events and involve spatial gradients in active cellular forces
induced by complex chemical signaling. Here, we introduce a mechanochemical model
based on the notion that cell shape changes may be induced by external diffusible
biomolecules that influence cellular contractility (or equivalently, adhesions)
in a concentration-dependent manner—and whose spatial profile in turn is affected
by cell shape. We map out theoretically the possible interplay between chemical
concentration and cellular structure. Besides providing a direct route to spatial
gradients in cell shape profiles in tissues, we show that the dependence on cell
shape helps create robust mechanochemical gradients.
