text: Embryogenesis results from the coordinated activities of different signaling
pathways controlling cell fate specification and morphogenesis. In vertebrate
gastrulation, both Nodal and BMP signaling play key roles in germ layer specification
and morphogenesis, yet their interplay to coordinate embryo patterning with morphogenesis
is still insufficiently understood. Here, we took a reductionist approach using
zebrafish embryonic explants to study the coordination of Nodal and BMP signaling
for embryo patterning and morphogenesis. We show that Nodal signaling triggers
explant elongation by inducing mesendodermal progenitors but also suppressing
BMP signaling activity at the site of mesendoderm induction. Consistent with this,
ectopic BMP signaling in the mesendoderm blocks cell alignment and oriented mesendoderm
intercalations, key processes during explant elongation. Translating these ex
vivo observations to the intact embryo showed that, similar to explants, Nodal
signaling suppresses the effect of BMP signaling on cell intercalations in the
dorsal domain, thus allowing robust embryonic axis elongation. These findings
suggest a dual function of Nodal signaling in embryonic axis elongation by both
inducing mesendoderm and suppressing BMP effects in the dorsal portion of the
mesendoderm.

abstract:
- lang: eng
text: The extracellular matrix (ECM) serves as a scaffold for cells and plays an
essential role in regulating numerous cellular processes, including cell migration
and proliferation. Due to limitations in specimen preparation for conventional
room-temperature electron microscopy, we lack structural knowledge on how ECM
components are secreted, remodeled, and interact with surrounding cells. We have
developed a 3D-ECM platform compatible with sample thinning by cryo-focused ion
beam milling, the lift-out extraction procedure, and cryo-electron tomography.
Our workflow implements cell-derived matrices (CDMs) grown on EM grids, resulting
in a versatile tool closely mimicking ECM environments. This allows us to visualize
ECM for the first time in its hydrated, native context. Our data reveal an intricate
network of extracellular fibers, their positioning relative to matrix-secreting
cells, and previously unresolved structural entities. Our workflow and results
add to the structural atlas of the ECM, providing novel insights into its secretion
and assembly.

text: Motile cells moving in multicellular organisms encounter microenvironments
of locally heterogeneous mechanochemical composition. Individual compositional
parameters like chemotactic signals, adhesiveness, and pore sizes are well known
to be sensed by motile cells, providing individual guidance cues for cellular
pathfinding. However, motile cells encounter diverse mechanochemical signals at
the same time, raising the question of how cells respond to locally diverse and
potentially competing signals on their migration routes. Here, we reveal that
motile amoeboid cells require nuclear repositioning, termed nucleokinesis, for
adaptive pathfinding in heterogeneous mechanochemical microenvironments. Using
mammalian immune cells and the amoebaDictyostelium discoideum,
we discover that frequent, rapid and long-distance nucleokinesis is a basic component
of amoeboid pathfinding, enabling cells to reorientate quickly between locally
competing cues. Amoeboid nucleokinesis comprises a two-step cell polarity switch
and is driven by myosin II-forces, sliding the nucleus from a ‘losing’ to the
‘winning’ leading edge to re-adjust the nuclear to the cellular path. Impaired
nucleokinesis distorts fast path adaptions and causes cellular arrest in the microenvironment.
Our findings establish that nucleokinesis is required for amoeboid cell navigation.
Given that motile single-cell amoebae, many immune cells, and some cancer cells
utilize an amoeboid migration strategy, these results suggest that amoeboid nucleokinesis
underlies cellular navigation during unicellular biology, immunity, and disease.

text: Singlet oxygen (1O2) formation is now recognised as a key aspect of non-aqueous
oxygen redox chemistry. For identifying 1O2, chemical trapping via 9,10-dimethylanthracene
(DMA) to form the endoperoxide (DMA-O2) has become the mainstay method due to
its sensitivity, selectivity, and ease of use. While DMA has been shown to be
selective for 1O2, rather than forming DMA-O2 with a wide variety of potentially
reactive O-containing species, false positives might hypothetically be obtained
in the presence of previously overlooked species. Here, we first give unequivocal
direct spectroscopic proof by the 1O2-specific near infrared (NIR) emission at
1270 nm for the previously proposed 1O2 formation pathways, which centre around
superoxide disproportionation. We then show that peroxocarbonates, common intermediates
in metal-O2 and metal carbonate electrochemistry, do not produce false-positive
DMA-O2. Moreover, we identify a previously unreported 1O2-forming pathway through
the reaction of CO2 with superoxide. Overall, we give unequivocal proof for 1O2
formation in non-aqueous oxygen redox and show that chemical trapping with DMA
is a reliable method to assess 1O2 formation.

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: Centrosomes play a crucial role during immune cell interactions and initiation
of the immune response. In proliferating cells, centrosome numbers are tightly
controlled and generally limited to one in G1 and two prior to mitosis. Defects
in regulating centrosome numbers have been associated with cell transformation
and tumorigenesis. Here, we report the emergence of extra centrosomes in leukocytes
during immune activation. Upon antigen encounter, dendritic cells pass through
incomplete mitosis and arrest in the subsequent G1 phase leading to tetraploid
cells with accumulated centrosomes. In addition, cell stimulation increases expression
of polo-like kinase 2, resulting in diploid cells with two centrosomes in G1-arrested
cells. During cell migration, centrosomes tightly cluster and act as functional
microtubule-organizing centers allowing for increased persistent locomotion along
gradients of chemotactic cues. Moreover, dendritic cells with extra centrosomes
display enhanced secretion of inflammatory cytokines and optimized T cell responses.
Together, these results demonstrate a previously unappreciated role of extra centrosomes
for regular cell and tissue homeostasis.

text: 'When crawling through the body, leukocytes often traverse tissues that are
densely packed with extracellular matrix and other cells, and this raises the
question: How do leukocytes overcome compressive mechanical loads? Here, we show
that the actin cortex of leukocytes is mechanoresponsive and that this responsiveness
requires neither force sensing via the nucleus nor adhesive interactions with
a substrate. Upon global compression of the cell body as well as local indentation
of the plasma membrane, Wiskott-Aldrich syndrome protein (WASp) assembles into
dot-like structures, providing activation platforms for Arp2/3 nucleated actin
patches. These patches locally push against the external load, which can be obstructing
collagen fibers or other cells, and thereby create space to facilitate forward
locomotion. We show in vitro and in vivo that this WASp function is rate limiting
for ameboid leukocyte migration in dense but not in loose environments and is
required for trafficking through diverse tissues such as skin and lymph nodes.'

text: Gradients of chemokines and growth factors guide migrating cells and morphogenetic
processes. Migration of antigen-presenting dendritic cells from the interstitium
into the lymphatic system is dependent on chemokine CCL21, which is secreted by
endothelial cells of the lymphatic capillary, binds heparan sulfates and forms
gradients decaying into the interstitium. Despite the importance of CCL21 gradients,
and chemokine gradients in general, the mechanisms of gradient formation are unclear.
Studies on fibroblast growth factors have shown that limited diffusion is crucial
for gradient formation. Here, we used the mouse dermis as a model tissue to address
the necessity of CCL21 anchoring to lymphatic capillary heparan sulfates in the
formation of interstitial CCL21 gradients. Surprisingly, the absence of lymphatic
endothelial heparan sulfates resulted only in a modest decrease of CCL21 levels
at the lymphatic capillaries and did neither affect interstitial CCL21 gradient
shape nor dendritic cell migration toward lymphatic capillaries. Thus, heparan
sulfates at the level of the lymphatic endothelium are dispensable for the formation
of a functional CCL21 gradient.

text: Attachment of adhesive molecules on cell culture surfaces to restrict cell
adhesion to defined areas and shapes has been vital for the progress of in vitro
research. In currently existing patterning methods, a combination of pattern properties
such as stability, precision, specificity, high-throughput outcome, and spatiotemporal
control is highly desirable but challenging to achieve. Here, we introduce a versatile
and high-throughput covalent photoimmobilization technique, comprising a light-dose-dependent
patterning step and a subsequent functionalization of the pattern via click chemistry.
This two-step process is feasible on arbitrary surfaces and allows for generation
of sustainable patterns and gradients. The method is validated in different biological
systems by patterning adhesive ligands on cell-repellent surfaces, thereby constraining
the growth and migration of cells to the designated areas. We then implement a
sequential photopatterning approach by adding a second switchable patterning step,
allowing for spatiotemporal control over two distinct surface patterns. As a proof
of concept, we reconstruct the dynamics of the tip/stalk cell switch during angiogenesis.
Our results show that the spatiotemporal control provided by our “sequential photopatterning”
system is essential for mimicking dynamic biological processes and that our innovative
approach has great potential for further applications in cell science.

text: Polar subcellular localization of the PIN exporters of the phytohormone auxin
is a key determinant of directional, intercellular auxin transport and thus a
central topic of both plant cell and developmental biology. Arabidopsis mutants
lacking PID, a kinase that phosphorylates PINs, or the MAB4/MEL proteins of unknown
molecular function display PIN polarity defects and phenocopy pin mutants, but
mechanistic insights into how these factors convey PIN polarity are missing. Here,
by combining protein biochemistry with quantitative live-cell imaging, we demonstrate
that PINs, MAB4/MELs, and AGC kinases interact in the same complex at the plasma
membrane. MAB4/MELs are recruited to the plasma membrane by the PINs and in concert
with the AGC kinases maintain PIN polarity through limiting lateral diffusion-based
escape of PINs from the polar domain. The PIN-MAB4/MEL-PID protein complex has
self-reinforcing properties thanks to positive feedback between AGC kinase-mediated
PIN phosphorylation and MAB4/MEL recruitment. We thus uncover the molecular mechanism
by which AGC kinases and MAB4/MEL proteins regulate PIN localization and plant
development.

text: A semiconducting nanowire fully wrapped by a superconducting shell has been
proposed as a platform for obtaining Majorana modes at small magnetic fields.
In this study, we demonstrate that the appearance of subgap states in such structures
is actually governed by the junction region in tunneling spectroscopy measurements
and not the full-shell nanowire itself. Short tunneling regions never show subgap
states, whereas longer junctions always do. This can be understood in terms of
quantum dots forming in the junction and hosting Andreev levels in the Yu-Shiba-Rusinov
regime. The intricate magnetic field dependence of the Andreev levels, through
both the Zeeman and Little-Parks effects, may result in robust zero-bias peaks—features
that could be easily misinterpreted as originating from Majorana zero modes but
are unrelated to topological superconductivity.

text: "Auxin is a major plant growth regulator, but current models on auxin perception
and signaling cannot explain the whole plethora of auxin effects, in particular
those associated with rapid responses. A possible candidate for a component of
additional auxin perception mechanisms is the AUXIN BINDING PROTEIN 1 (ABP1),
whose function in planta remains unclear.\r\nHere we combined expression analysis
with gain- and loss-of-function approaches to analyze the role of ABP1 in plant
development. ABP1 shows a broad expression largely overlapping with, but not regulated
by, transcriptional auxin response activity. Furthermore, ABP1 activity is not
essential for the transcriptional auxin signaling. Genetic in planta analysis
revealed that abp1 loss-of-function mutants show largely normal development with
minor defects in bolting. On the other hand, ABP1 gain-of-function alleles show
a broad range of growth and developmental defects, including root and hypocotyl
growth and bending, lateral root and leaf development, bolting, as well as response
to heat stress. At the cellular level, ABP1 gain-of-function leads to impaired
auxin effect on PIN polar distribution and affects BFA-sensitive PIN intracellular
aggregation.\r\nThe gain-of-function analysis suggests a broad, but still mechanistically
unclear involvement of ABP1 in plant development, possibly masked in abp1 loss-of-function
mutants by a functional redundancy."

abstract:

text: 'Cells navigating through complex tissues face a fundamental challenge: while
multiple protrusions explore different paths, the cell needs to avoid entanglement.
How a cell surveys and then corrects its own shape is poorly understood. Here,
we demonstrate that spatially distinct microtubule dynamics regulate amoeboid
cell migration by locally promoting the retraction of protrusions. In migrating
dendritic cells, local microtubule depolymerization within protrusions remote
from the microtubule organizing center triggers actomyosin contractility controlled
by RhoA and its exchange factor Lfc. Depletion of Lfc leads to aberrant myosin
localization, thereby causing two effects that rate-limit locomotion: (1) impaired
cell edge coordination during path finding and (2) defective adhesion resolution.
Compromised shape control is particularly hindering in geometrically complex microenvironments,
where it leads to entanglement and ultimately fragmentation of the cell body.
We thus demonstrate that microtubules can act as a proprioceptive device: they
sense cell shape and control actomyosin retraction to sustain cellular coherence.'

text: Embryonic stem cell cultures are thought to self-organize into embryoid bodies,
able to undergo symmetry-breaking, germ layer specification and even morphogenesis.
Yet, it is unclear how to reconcile this remarkable self-organization capacity
with classical experiments demonstrating key roles for extrinsic biases by maternal
factors and/or extraembryonic tissues in embryogenesis. Here, we show that zebrafish
embryonic tissue explants, prepared prior to germ layer induction and lacking
extraembryonic tissues, can specify all germ layers and form a seemingly complete
mesendoderm anlage. Importantly, explant organization requires polarized inheritance
of maternal factors from dorsal-marginal regions of the blastoderm. Moreover,
induction of endoderm and head-mesoderm, which require peak Nodal-signaling levels,
is highly variable in explants, reminiscent of embryos with reduced Nodal signals
from the extraembryonic tissues. Together, these data suggest that zebrafish explants
do not undergo bona fide self-organization, but rather display features of genetically
encoded self-assembly, where intrinsic genetic programs control the emergence
of order.

text: Cryo-electron microscopy (cryo-EM) of cellular specimens provides insights
into biological processes and structures within a native context. However, a major
challenge still lies in the efficient and reproducible preparation of adherent
cells for subsequent cryo-EM analysis. This is due to the sensitivity of many
cellular specimens to the varying seeding and culturing conditions required for
EM experiments, the often limited amount of cellular material and also the fragility
of EM grids and their substrate. Here, we present low-cost and reusable 3D printed
grid holders, designed to improve specimen preparation when culturing challenging
cellular samples directly on grids. The described grid holders increase cell culture
reproducibility and throughput, and reduce the resources required for cell culturing.
We show that grid holders can be integrated into various cryo-EM workflows, including
micro-patterning approaches to control cell seeding on grids, and for generating
samples for cryo-focused ion beam milling and cryo-electron tomography experiments.
Their adaptable design allows for the generation of specialized grid holders customized
to a large variety of applications.

text: Eukaryotic cells migrate by coupling the intracellular force of the actin
cytoskeleton to the environment. While force coupling is usually mediated by transmembrane
adhesion receptors, especially those of the integrin family, amoeboid cells such
as leukocytes can migrate extremely fast despite very low adhesive forces1. Here
we show that leukocytes cannot only migrate under low adhesion but can also transmit
forces in the complete absence of transmembrane force coupling. When confined
within three-dimensional environments, they use the topographical features of
the substrate to propel themselves. Here the retrograde flow of the actin cytoskeleton
follows the texture of the substrate, creating retrograde shear forces that are
sufficient to drive the cell body forwards. Notably, adhesion-dependent and adhesion-independent
migration are not mutually exclusive, but rather are variants of the same principle
of coupling retrograde actin flow to the environment and thus can potentially
operate interchangeably and simultaneously. As adhesion-free migration is independent
of the chemical composition of the environment, it renders cells completely autonomous
in their locomotive behaviour.

text: During metazoan development, immune surveillance and cancer dissemination,
cells migrate in complex three-dimensional microenvironments1,2,3. These spaces
are crowded by cells and extracellular matrix, generating mazes with differently
sized gaps that are typically smaller than the diameter of the migrating cell4,5.
Most mesenchymal and epithelial cells and some—but not all—cancer cells actively
generate their migratory path using pericellular tissue proteolysis6. By contrast,
amoeboid cells such as leukocytes use non-destructive strategies of locomotion7,
raising the question how these extremely fast cells navigate through dense tissues.
Here we reveal that leukocytes sample their immediate vicinity for large pore
sizes, and are thereby able to choose the path of least resistance. This allows
them to circumnavigate local obstacles while effectively following global directional
cues such as chemotactic gradients. Pore-size discrimination is facilitated by
frontward positioning of the nucleus, which enables the cells to use their bulkiest
compartment as a mechanical gauge. Once the nucleus and the closely associated
microtubule organizing centre pass the largest pore, cytoplasmic protrusions still
lingering in smaller pores are retracted. These retractions are coordinated by
dynamic microtubules; when microtubules are disrupted, migrating cells lose coherence
and frequently fragment into migratory cytoplasmic pieces. As nuclear positioning
in front of the microtubule organizing centre is a typical feature of amoeboid
migration, our findings link the fundamental organization of cellular polarity
to the strategy of locomotion.

text: Dendritic cells (DCs) are sentinels of the adaptive immune system that reside
in peripheral organs of mammals. Upon pathogen encounter, they undergo maturation
and up-regulate the chemokine receptor CCR7 that guides them along gradients of
its chemokine ligands CCL19 and 21 to the next draining lymph node. There, DCs
present peripherally acquired antigen to naïve T cells, thereby triggering adaptive
immunity.

text: Lymphatic endothelial cells (LECs) release extracellular chemokines to guide
the migration of dendritic cells. In this study, we report that LECs also release
basolateral exosome-rich endothelial vesicles (EEVs) that are secreted in greater
numbers in the presence of inflammatory cytokines and accumulate in the perivascular
stroma of small lymphatic vessels in human chronic inflammatory diseases. Proteomic
analyses of EEV fractions identified > 1,700 cargo proteins and revealed a
dominant motility-promoting protein signature. In vitro and ex vivo EEV fractions
augmented cellular protrusion formation in a CX3CL1/fractalkine-dependent fashion
and enhanced the directional migratory response of human dendritic cells along
guidance cues. We conclude that perilymphatic LEC exosomes enhance exploratory
behavior and thus promote directional migration of CX3CR1-expressing cells in
complex tissue environments.

text: Although much is known about the physiological framework of T cell motility,
and numerous rate-limiting molecules have been identified through loss-of-function
approaches, an integrated functional concept of T cell motility is lacking. Here,
we used in vivo precision morphometry together with analysis of cytoskeletal dynamics
in vitro to deconstruct the basic mechanisms of T cell migration within lymphatic
organs. We show that the contributions of the integrin LFA-1 and the chemokine
receptor CCR7 are complementary rather than positioned in a linear pathway, as
they are during leukocyte extravasation from the blood vasculature. Our data demonstrate
that CCR7 controls cortical actin flows, whereas integrins mediate substrate friction
that is sufficient to drive locomotion in the absence of considerable surface
adhesions and plasma membrane flux.

text: Trafficking cells frequently transmigrate through epithelial and endothelial
monolayers. How monolayers cooperate with the penetrating cells to support their
transit is poorly understood. We studied dendritic cell (DC) entry into lymphatic
capillaries as a model system for transendothelial migration. We find that the
chemokine CCL21, which is the decisive guidance cue for intravasation, mainly
localizes in the trans-Golgi network and intracellular vesicles of lymphatic endothelial
cells. Upon DC transmigration, these Golgi deposits disperse and CCL21 becomes
extracellularly enriched at the sites of endothelial cell-cell junctions. When
we reconstitute the transmigration process in vitro, we find that secretion of
CCL21-positive vesicles is triggered by a DC contact-induced calcium signal, and
selective calcium chelation in lymphatic endothelium attenuates transmigration.
Altogether, our data demonstrate a chemokine-mediated feedback between DCs and
lymphatic endothelium, which facilitates transendothelial migration.

text: Navigation of cells along gradients of guidance cues is a determining step
in many developmental and immunological processes. Gradients can either be soluble
or immobilized to tissues as demonstrated for the haptotactic migration of dendritic
cells (DCs) toward higher concentrations of immobilized chemokine CCL21. To elucidate
how gradient characteristics govern cellular response patterns, we here introduce
an in vitro system allowing to track migratory responses of DCs to precisely controlled
immobilized gradients of CCL21. We find that haptotactic sensing depends on the
absolute CCL21 concentration and local steepness of the gradient, consistent with
a scenario where DC directionality is governed by the signal-to-noise ratio of
CCL21 binding to the receptor CCR7. We find that the conditions for optimal DC
guidance are perfectly provided by the CCL21 gradients we measure in vivo. Furthermore,
we find that CCR7 signal termination by the G-protein-coupled receptor kinase
6 (GRK6) is crucial for haptotactic but dispensable for chemotactic CCL21 gradient
sensing in vitro and confirm those observations in vivo. These findings suggest
that stable, tissue-bound CCL21 gradients as sustainable “roads” ensure optimal
guidance in vivo.

text: 'Actin filaments polymerizing against membranes power endocytosis, vesicular
traffic, and cell motility. In vitro reconstitution studies suggest that the structure
and the dynamics of actin networks respond to mechanical forces. We demonstrate
that lamellipodial actin of migrating cells responds to mechanical load when membrane
tension is modulated. In a steady state, migrating cell filaments assume the canonical
dendritic geometry, defined by Arp2/3-generated 70° branch points. Increased tension
triggers a dense network with a broadened range of angles, whereas decreased tension
causes a shift to a sparse configuration dominated by filaments growing perpendicularly
to the plasma membrane. We show that these responses emerge from the geometry
of branched actin: when load per filament decreases, elongation speed increases
and perpendicular filaments gradually outcompete others because they polymerize
the shortest distance to the membrane, where they are protected from capping.
This network-intrinsic geometrical adaptation mechanism tunes protrusive force
in response to mechanical load.'

text: The molecular mechanisms underlying phenotypic variation in isogenic bacterial
populations remain poorly understood.We report that AcrAB-TolC, the main multidrug
efflux pump of Escherichia coli, exhibits a strong partitioning bias for old cell
poles by a segregation mechanism that is mediated by ternary AcrAB-TolC complex
formation. Mother cells inheriting old poles are phenotypically distinct and display
increased drug efflux activity relative to daughters. Consequently, we find systematic
and long-lived growth differences between mother and daughter cells in the presence
of subinhibitory drug concentrations. A simple model for biased partitioning predicts
a population structure of long-lived and highly heterogeneous phenotypes. This
straightforward mechanism of generating sustained growth rate differences at subinhibitory
antibiotic concentrations has implications for understanding the emergence of
multidrug resistance in bacteria.

text: Roots navigate through soil integrating environmental signals to orient their
growth. The Arabidopsis root is a widely used model for developmental, physiological
and cell biological studies. Live imaging greatly aids these efforts, but the
horizontal sample position and continuous root tip displacement present significant
difficulties. Here, we develop a confocal microscope setup for vertical sample
mounting and integrated directional illumination. We present TipTracker – a custom
software for automatic tracking of diverse moving objects usable on various microscope
setups. Combined, this enables observation of root tips growing along the natural
gravity vector over prolonged periods of time, as well as the ability to induce
rapid gravity or light stimulation. We also track migrating cells in the developing
zebrafish embryo, demonstrating the utility of this system in the acquisition
of high-resolution data sets of dynamic samples. We provide detailed descriptions
of the tools enabling the easy implementation on other microscopes.

text: 'One of the key questions in understanding plant development is how single
cells behave in a larger context of the tissue. Therefore, it requires the observation

sample preparation method for light-sheet microscopy, which is characterized by
mounting the plant vertically on the surface of a gel. The plant is mounted in
such a way that the roots are submerged in a liquid medium while the leaves remain

text: "Cellular locomotion is a central hallmark of eukaryotic life. It is governed
by cell-extrinsic molecular factors, which can either emerge in the soluble phase
or as immobilized, often adhesive ligands. To encode for direction, every cue
must be present as a spatial or temporal gradient. Here, we developed a microfluidic
chamber that allows measurement of cell migration in combined response to surface
immobilized and soluble molecular gradients. As a proof of principle we study
the response of dendritic cells to their major guidance cues, chemokines. The
majority of data on chemokine gradient sensing is based on in vitro studies employing
soluble gradients. Despite evidence suggesting that in vivo chemokines are often
immobilized to sugar residues, limited information is available how cells respond
to immobilized chemokines. We tracked migration of dendritic cells towards immobilized
gradients of the chemokine CCL21 and varying superimposed soluble gradients of
CCL19. Differential migratory patterns illustrate the potential of our setup to
quantitatively study the competitive response to both types of gradients. Beyond
chemokines our approach is broadly applicable to alternative systems of chemo-
and haptotaxis such as cells migrating along gradients of adhesion receptor ligands
vs. any soluble cue. \r\n"

text: Most migrating cells extrude their front by the force of actin polymerization.
Polymerization requires an initial nucleation step, which is mediated by factors
establishing either parallel filaments in the case of filopodia or branched filaments
that form the branched lamellipodial network. Branches are considered essential
for regular cell motility and are initiated by the Arp2/3 complex, which in turn
is activated by nucleation-promoting factors of the WASP and WAVE families. Here
we employed rapid amoeboid crawling leukocytes and found that deletion of the
WAVE complex eliminated actin branching and thus lamellipodia formation. The cells
were left with parallel filaments at the leading edge, which translated, depending
on the differentiation status of the cell, into a unipolar pointed cell shape
or cells with multiple filopodia. Remarkably, unipolar cells migrated with increased
speed and enormous directional persistence, while they were unable to turn towards
chemotactic gradients. Cells with multiple filopodia retained chemotactic activity
but their migration was progressively impaired with increasing geometrical complexity
of the extracellular environment. These findings establish that diversified leading
edge protrusions serve as explorative structures while they slow down actual locomotion.

text: The prominent and evolutionarily ancient role of the plant hormone auxin is
the regulation of cell expansion. Cell expansion requires ordered arrangement
of the cytoskeleton but molecular mechanisms underlying its regulation by signalling
molecules including auxin are unknown. Here we show in the model plant Arabidopsis
thaliana that in elongating cells exogenous application of auxin or redistribution
of endogenous auxin induces very rapid microtubule re-orientation from transverse
to longitudinal, coherent with the inhibition of cell expansion. This fast auxin
effect requires auxin binding protein 1 (ABP1) and involves a contribution of
downstream signalling components such as ROP6 GTPase, ROP-interactive protein
RIC1 and the microtubule-severing protein katanin. These components are required
for rapid auxin-and ABP1-mediated re-orientation of microtubules to regulate cell
elongation in roots and dark-grown hypocotyls as well as asymmetric growth during
gravitropic responses.

text: Directional guidance of cells via gradients of chemokines is considered crucial
for embryonic development, cancer dissemination, and immune responses. Nevertheless,
the concept still lacks direct experimental confirmation in vivo. Here, we identify
endogenous gradients of the chemokine CCL21 within mouse skin and show that they
guide dendritic cells toward lymphatic vessels. Quantitative imaging reveals depots
of CCL21 within lymphatic endothelial cells and steeply decaying gradients within
the perilymphatic interstitium. These gradients match the migratory patterns of
the dendritic cells, which directionally approach vessels from a distance of up
to 90-micrometers. Interstitial CCL21 is immobilized to heparan sulfates, and
its experimental delocalization or swamping the endogenous gradients abolishes
directed migration. These findings functionally establish the concept of haptotaxis,
directed migration along immobilized gradients, in tissues.

text: Contractile actomyosin rings drive various fundamental morphogenetic processes
ranging from cytokinesis to wound healing. Actomyosin rings are generally thought
to function by circumferential contraction. Here, we show that the spreading of
the enveloping cell layer (EVL) over the yolk cell during zebrafish gastrulation
is driven by a contractile actomyosin ring. In contrast to previous suggestions,
we find that this ring functions not only by circumferential contraction but also
by a flow-friction mechanism. This generates a pulling force through resistance
against retrograde actomyosin flow. EVL spreading proceeds normally in situations
where circumferential contraction is unproductive, indicating that the flow-friction
mechanism is sufficient. Thus, actomyosin rings can function in epithelial morphogenesis
through a combination of cable-constriction and flow-friction mechanisms.
