text: Glycoinositolphosphoceramides (GIPCs) are complex sphingolipids present at
the plasma membrane of various eukaryotes with the important exception of mammals.
In fungi, these glycosphingolipids commonly contain an alpha-mannose residue (Man)
linked at position 2 of the inositol. However, several pathogenic fungi additionally
synthesize zwitterionic GIPCs carrying an alpha-glucosamine residue (GlcN) at
this position. In the human pathogen Aspergillus fumigatus, the GlcNalpha1,2IPC
core (where IPC is inositolphosphoceramide) is elongated to Manalpha1,3Manalpha1,6GlcNalpha1,2IPC,
which is the most abundant GIPC synthesized by this fungus. In this study, we
identified an A. fumigatus N-acetylglucosaminyltransferase, named GntA, and demonstrate
its involvement in the initiation of zwitterionic GIPC biosynthesis. Targeted
deletion of the gene encoding GntA in A. fumigatus resulted in complete absence
of zwitterionic GIPC; a phenotype that could be reverted by episomal expression
of GntA in the mutant. The N-acetylhexosaminyltransferase activity of GntA was
substantiated by production of N-acetylhexosamine-IPC in the yeast Saccharomyces
cerevisiae upon GntA expression. Using an in vitro assay, GntA was furthermore
shown to use UDP-N-acetylglucosamine as donor substrate to generate a glycolipid
product resistant to saponification and to digestion by phosphatidylinositol-phospholipase
C as expected for GlcNAcalpha1,2IPC. Finally, as the enzymes involved in mannosylation
of IPC, GntA was localized to the Golgi apparatus, the site of IPC synthesis.

text: Deposits of misfolded proteins in the human brain are associated with the
development of many neurodegenerative diseases. Recent studies show that these
proteins have common traits even at the monomer level. Among them, a polyglutamine
region that is present in huntingtin is known to exhibit a correlation between
the length of the chain and the severity as well as the earliness of the onset
of Huntington disease. Here, we apply bias exchange molecular dynamics to generate
structures of polyglutamine expansions of several lengths and characterize the
resulting independent conformations. We compare the properties of these conformations
to those of the standard proteins, as well as to other homopolymeric tracts. We
find that, similar to the previously studied polyvaline chains, the set of possible
transient folds is much broader than the set of known-to-date folds, although
the conformations have different structures. We show that the mechanical stability
is not related to any simple geometrical characteristics of the structures. We
demonstrate that long polyglutamine expansions result in higher mechanical stability
than the shorter ones. They also have a longer life span and are substantially
more prone to form knotted structures. The knotted region has an average length
of 35 residues, similar to the typical threshold for most polyglutamine-related
diseases. Similarly, changes in shape and mechanical stability appear once the
total length of the peptide exceeds this threshold of 35 glutamine residues. We
suggest that knotted conformers may also harm the cellular machinery and thus
lead to disease.

text: 3D amoeboid cell migration is central to many developmental and disease-related
processes such as cancer metastasis. Here, we identify a unique prototypic amoeboid
cell migration mode in early zebrafish embryos, termed stable-bleb migration.
Stable-bleb cells display an invariant polarized balloon-like shape with exceptional
migration speed and persistence. Progenitor cells can be reversibly transformed
into stable-bleb cells irrespective of their primary fate and motile characteristics
by increasing myosin II activity through biochemical or mechanical stimuli. Using
a combination of theory and experiments, we show that, in stable-bleb cells, cortical
contractility fluctuations trigger a stochastic switch into amoeboid motility,
and a positive feedback between cortical flows and gradients in contractility
maintains stable-bleb cell polarization. We further show that rearward cortical
flows drive stable-bleb cell migration in various adhesive and non-adhesive environments,
unraveling a highly versatile amoeboid migration phenotype.

text: In the last several decades, developmental biology has clarified the molecular
mechanisms of embryogenesis and organogenesis. In particular, it has demonstrated
that the “tool-kit genes” essential for regulating developmental processes are
not only highly conserved among species, but are also used as systems at various
times and places in an organism to control distinct developmental events. Therefore,
mutations in many of these tool-kit genes may cause congenital diseases involving
morphological abnormalities. This link between genes and abnormal morphological
phenotypes underscores the importance of understanding how cells behave and contribute
to morphogenesis as a result of gene function. Recent improvements in live imaging
and in quantitative analyses of cellular dynamics will advance our understanding
of the cellular pathogenesis of congenital diseases associated with aberrant morphologies.
In these studies, it is critical to select an appropriate model organism for the
particular phenomenon of interest.

text: We provide theoretical tests of a novel experimental technique to determine
mechanostability of proteins based on stretching a mechanically protected protein
by single-molecule force spectroscopy. This technique involves stretching a homogeneous
or heterogeneous chain of reference proteins (single-molecule markers) in which
one of them acts as host to the guest protein under study. The guest protein is
grafted into the host through genetic engineering. It is expected that unraveling
of the host precedes the unraveling of the guest removing ambiguities in the reading
of the force-extension patterns of the guest protein. We study examples of such
systems within a coarse-grained structure-based model. We consider systems with
various ratios of mechanostability for the host and guest molecules and compare
them to experimental results involving cohesin I as the guest molecule. For a
comparison, we also study the force-displacement patterns in proteins that are
linked in a serial fashion. We find that the mechanostability of the guest is
similar to that of the isolated or serially linked protein. We also demonstrate
that the ideal configuration of this strategy would be one in which the host is
much more mechanostable than the single-molecule markers. We finally show that
it is troublesome to use the highly stable cystine knot proteins as a host to
graft a guest in stretching studies because this would involve a cleaving procedure.

text: Epithelial cell layers need to be tightly regulated to maintain their integrity
and correct function. Cell integration into epithelial sheets is now shown to
depend on the N-WASP-regulated stabilization of cortical F-actin, which generates
distinct patterns of apical-lateral contractility at E-cadherin-based cell-cell
junctions.

text: In the past decade carbon nanotubes (CNTs) have been widely studied as a potential
drug-delivery system, especially with functionality for cellular targeting. Yet,
little is known about the actual process of docking to cell receptors and transport
dynamics after internalization. Here we performed single-particle studies of folic
acid (FA) mediated CNT binding to human carcinoma cells and their transport inside
the cytosol. In particular, we employed molecular recognition force spectroscopy,
an atomic force microscopy based method, to visualize and quantify docking of
FA functionalized CNTs to FA binding receptors in terms of binding probability
and binding force. We then traced individual fluorescently labeled, FA functionalized
CNTs after specific uptake, and created a dynamic 'roadmap' that clearly showed
trajectories of directed diffusion and areas of nanotube confinement in the cytosol.
Our results demonstrate the potential of a single-molecule approach for investigation
of drug-delivery vehicles and their targeting capacity.

text: We derive the equations for a thin, axisymmetric elastic shell subjected to
an internal active stress giving rise to active tension and moments within the
shell. We discuss the stability of a cylindrical elastic shell and its response
to a localized change in internal active stress. This description is relevant
to describe the cellular actomyosin cortex, a thin shell at the cell surface behaving
elastically at a short timescale and subjected to active internal forces arising
from myosin molecular motor activity. We show that the recent observations of
cell deformation following detachment of adherent cells (Maître J-L et al 2012
Science 338 253-6) are well accounted for by this mechanical description. The
actin cortex elastic and bending moduli can be obtained from a quantitative analysis
of cell shapes observed in these experiments. Our approach thus provides a non-invasive,
imaging-based method for the extraction of cellular physical parameters.

text: 'Avian forelimb digit homology remains one of the standard themes in comparative
biology and EvoDevo research. In order to resolve the apparent contradictions
between embryological and paleontological evidence a variety of hypotheses have
been presented in recent years. The proposals range from excluding birds from
the dinosaur clade, to assignments of homology by different criteria, or even
assuming a hexadactyl tetrapod limb ground state. At present two approaches prevail:
the frame shift hypothesis and the pyramid reduction hypothesis. While the former
postulates a homeotic shift of digit identities, the latter argues for a gradual
bilateral reduction of phalanges and digits. Here we present a new model that
integrates elements from both hypotheses with the existing experimental and fossil
evidence. We start from the main feature common to both earlier concepts, the
initiating ontogenetic event: reduction and loss of the anterior-most digit. It
is proposed that a concerted mechanism of molecular regulation and developmental
mechanics is capable of shifting the boundaries of hoxD expression in embryonic
forelimb buds as well as changing the digit phenotypes. Based on a distinction
between positional (topological) and compositional (phenotypic) homology criteria,
we argue that the identity of the avian digits is II, III, IV, despite a partially
altered phenotype. Finally, we introduce an alternative digit reduction scheme
that reconciles the current fossil evidence with the presented molecular-morphogenetic
model. Our approach identifies specific experiments that allow to test whether
gene expression can be shifted and digit phenotypes can be altered by induced
digit loss or digit gain.'

text: Mechanically coupled cells can generate forces driving cell and tissue morphogenesis
during development. Visualization and measuring of these forces is of major importance
to better understand the complexity of the biomechanic processes that shape cells
and tissues. Here, we describe how UV laser ablation can be utilized to quantitatively
assess mechanical tension in different tissues of the developing zebrafish and
in cultures of primary germ layer progenitor cells ex vivo.

text: Kupffer's vesicle (KV) is the zebrafish organ of laterality, patterning the
embryo along its left-right (LR) axis. Regional differences in cell shape within
the lumen-lining KV epithelium are essential for its LR patterning function. However,
the processes by which KV cells acquire their characteristic shapes are largely
unknown. Here, we show that the notochord induces regional differences in cell
shape within KV by triggering extracellular matrix (ECM) accumulation adjacent
to anterior-dorsal (AD) regions of KV. This localized ECM deposition restricts
apical expansion of lumen-lining epithelial cells in AD regions of KV during lumen
growth. Our study provides mechanistic insight into the processes by which KV
translates global embryonic patterning into regional cell shape differences required
for its LR symmetry-breaking function.

text: A variety of developmental and disease related processes depend on epithelial
cell sheet spreading. In order to gain insight into the biophysical mechanism(s)
underlying the tissue morphogenesis we studied the spreading of an epithelium
during the early development of the zebrafish embryo. In zebrafish epiboly the
enveloping cell layer (EVL), a simple squamous epithelium, spreads over the yolk
cell to completely engulf it at the end of gastrulation. Previous studies have
proposed that an actomyosin ring forming within the yolk syncytial layer (YSL)
acts as purse string that through constriction along its circumference pulls on
the margin of the EVL. Direct biophysical evidence for this hypothesis has however
been missing. The aim of the thesis was to understand how the actomyosin ring
may generate pulling forces onto the EVL and what cellular mechanism(s) may facilitate
the spreading of the epithelium. Using laser ablation to measure cortical tension
within the actomyosin ring we found an anisotropic tension distribution, which
was highest along the circumference of the ring. However the low degree of anisotropy
was incompatible with the actomyosin ring functioning as a purse string only.
Additionally, we observed retrograde cortical flow from vegetal parts of the ring
into the EVL margin. Interpreting the experimental data using a theoretical distribution
that models the tissues as active viscous gels led us to proposen that the actomyosin
ring has a twofold contribution to EVL epiboly. It not only acts as a purse string
through constriction along its circumference, but in addition constriction along
the width of the ring generates pulling forces through friction-resisted cortical
flow. Moreover, when rendering the purse string mechanism unproductive EVL epiboly
proceeded normally indicating that the flow-friction mechanism is sufficient to
drive the process. Aiming to understand what cellular mechanism(s) may facilitate
the spreading of the epithelium we found that tension-oriented EVL cell divisions
limit tissue anisotropy by releasing tension along the division axis and promote
epithelial spreading. Notably, EVL cells undergo ectopic cell fusion in conditions
in which oriented-cell division is impaired or the epithelium is mechanically
challenged. Taken together our study of EVL epiboly suggests a novel mechanism
of force generation for actomyosin rings through friction-resisted cortical flow
and highlights the importance of tension-oriented cell divisions in epithelial
morphogenesis.

text: It is firmly established that interactions between neurons and glia are fundamental
across species for the correct establishment of a functional brain. Here, we found
that the glia of the Drosophila larval brain display an essential non-autonomous
role during the development of the optic lobe. The optic lobe develops from neuroepithelial
cells that proliferate by dividing symmetrically until they switch to asymmetric/differentiative
divisions that generate neuroblasts. The proneural gene lethal of scute (l9sc)
is transiently activated by the epidermal growth factor receptor (EGFR)-Ras signal
transduction pathway at the leading edge of a proneural wave that sweeps from
medial to lateral neuroepithelium, promoting this switch. This process is tightly
regulated by the tissue-autonomous function within the neuroepithelium of multiple
signaling pathways, including EGFR-Ras and Notch. This study shows that the Notch
ligand Serrate (Ser) is expressed in the glia and it forms a complex in vivo with
Notch and Canoe, which colocalize at the adherens junctions of neuroepithelial
cells. This complex is crucial for interactions between glia and neuroepithelial
cells during optic lobe development. Ser is tissue-autonomously required in the
glia where it activates Notch to regulate its proliferation, and non-autonomously
in the neuroepithelium where Ser induces Notch signaling to avoid the premature
activation of the EGFR-Ras pathway and hence of L9sc. Interestingly, different
Notch activity reporters showed very different expression patterns in the glia
and in the neuroepithelium, suggesting the existence of tissue-specific factors
that promote the expression of particular Notch target genes or/and a reporter
response dependent on different thresholds of Notch signaling.

text: Epithelial spreading is a common and fundamental aspect of various developmental
and disease-related processes such as epithelial closure and wound healing. A
key challenge for epithelial tissues undergoing spreading is to increase their
surface area without disrupting epithelial integrity. Here we show that orienting
cell divisions by tension constitutes an efficient mechanism by which the enveloping
cell layer (EVL) releases anisotropic tension while undergoing spreading during
zebrafish epiboly. The control of EVL cell-division orientation by tension involves
cell elongation and requires myosin II activity to align the mitotic spindle with
the main tension axis. We also found that in the absence of tension-oriented cell
divisions and in the presence of increased tissue tension, EVL cells undergo ectopic
fusions, suggesting that the reduction of tension anisotropy by oriented cell
divisions is required to prevent EVL cells from fusing. We conclude that cell-division
orientation by tension constitutes a key mechanism for limiting tension anisotropy
and thus promoting tissue spreading during EVL epiboly.

text: The spatiotemporal control of cell divisions is a key factor in epithelial
morphogenesis and patterning. Mao et al (2013) now describe how differential rates
of proliferation within the Drosophila wing disc epithelium give rise to anisotropic
tissue tension in peripheral/proximal regions of the disc. Such global tissue
tension anisotropy in turn determines the orientation of cell divisions by controlling
epithelial cell elongation.

text: Cadherins are transmembrane proteins that mediate cell–cell adhesion in animals.
By regulating contact formation and stability, cadherins play a crucial role in
tissue morphogenesis and homeostasis. Here, we review the three major unctions
of cadherins in cell–cell contact formation and stability. Two of those functions
lead to a decrease in interfacial ension at the forming cell–cell contact, thereby
promoting contact expansion — first, by providing adhesion tension that lowers
interfacial tension at the cell–cell contact, and second, by signaling to the
actomyosin cytoskeleton in order to reduce cortex tension and thus interfacial
tension at the contact. The third function of cadherins in cell–cell contact formation
is to stabilize the contact by resisting mechanical forces that pull on the contact.

abstract:
- lang: eng
text: During development, mechanical forces cause changes in size, shape, number,
position, and gene expression of cells. They are therefore integral to any morphogenetic
processes. Force generation by actin-myosin networks and force transmission through
adhesive complexes are two self-organizing phenomena driving tissue morphogenesis.
Coordination and integration of forces by long-range force transmission and mechanosensing
of cells within tissues produce large-scale tissue shape changes. Extrinsic mechanical
forces also control tissue patterning by modulating cell fate specification and
differentiation. Thus, the interplay between tissue mechanics and biochemical
signaling orchestrates tissue morphogenesis and patterning in development.

text: Motile cilia perform crucial functions during embryonic development and throughout
adult life. Development of organs containing motile cilia involves regulation
of cilia formation (ciliogenesis) and formation of a luminal space (lumenogenesis)
in which cilia generate fluid flows. Control of ciliogenesis and lumenogenesis
is not yet fully understood, and it remains unclear whether these processes are
coupled. In the zebrafish embryo, lethal giant larvae 2 (lgl2) is expressed prominently
in ciliated organs. Lgl proteins are involved in establishing cell polarity and
have been implicated in vesicle trafficking. Here, we identified a role for Lgl2
in development of ciliated epithelia in Kupffer's vesicle, which directs left-right
asymmetry of the embryo; the otic vesicles, which give rise to the inner ear;
and the pronephric ducts of the kidney. Using Kupffer's vesicle as a model ciliated
organ, we found that depletion of Lgl2 disrupted lumen formation and reduced cilia
number and length. Immunofluorescence and time-lapse imaging of Kupffer's vesicle
morphogenesis in Lgl2-deficient embryos suggested cell adhesion defects and revealed
loss of the adherens junction component E-cadherin at lateral membranes. Genetic
interaction experiments indicate that Lgl2 interacts with Rab11a to regulate E-cadherin
and mediate lumen formation that is uncoupled from cilia formation. These results
uncover new roles and interactions for Lgl2 that are crucial for both lumenogenesis
and ciliogenesis and indicate that these processes are genetically separable in
zebrafish.

text: "Oriented mitosis is essential during tissue morphogenesis. The Wnt/planar
cell polarity (Wnt/PCP) pathway orients mitosis in a number of developmental systems,
including dorsal epiblast cell divisions along the animal-vegetal (A-V) axis during
zebrafish gastrulation. How Wnt signalling orients the mitotic plane is, however,
unknown. Here we show that, in dorsal epiblast cells, anthrax toxin receptor 2a
(Antxr2a) accumulates in a polarized cortical cap, which is aligned with the embryonic
A-V axis and forecasts the division plane. Filamentous actin (F-actin) also forms
an A-V polarized cap, which depends on Wnt/PCP and its effectors RhoA and Rock2.
Antxr2a is recruited to the cap by interacting with actin. Antxr2a also interacts
with RhoA and together they activate the diaphanous-related formin zDia2. Mechanistically,
Antxr2a functions as a Wnt-dependent polarized determinant, which, through the
action of RhoA and zDia2, exerts torque on the spindle to align it with the A-V
axis.\r\n"

text: Cell polarisation in development is a common and fundamental process underlying
embryo patterning and morphogenesis, and has been extensively studied over the
past years. Our current knowledge of cell polarisation in development is predominantly
based on studies that have analysed polarisation of single cells, such as eggs,
or cellular aggregates with a stable polarising interface, such as cultured epithelial
cells (St Johnston and Ahringer, 2010). However, in embryonic development, particularly
of vertebrates, cell polarisation processes often encompass large numbers of cells
that are placed within moving and proliferating tissues, and undergo mesenchymal-to-epithelial
transitions with a highly complex spatiotemporal choreography. How such intricate
cell polarisation processes in embryonic development are achieved has only started
to be analysed. By using live imaging of neurulation in the transparent zebrafish
embryo, Buckley et al (2012) now describe a novel polarisation strategy by which
cells assemble an apical domain in the part of their cell body that intersects
with the midline of the forming neural rod. This mechanism, along with the previously
described mirror-symmetric divisions (Tawk et al, 2007), is thought to trigger
formation of both neural rod midline and lumen.

text: Epithelial spreading is a critical part of various developmental and wound
repair processes. Here we use zebrafish epiboly as a model system to study the
cellular and molecular mechanisms underlying the spreading of epithelial sheets.
During zebrafish epiboly the enveloping cell layer (EVL), a simple squamous epithelium,
spreads over the embryo to eventually cover the entire yolk cell by the end of
gastrulation. The EVL leading edge is anchored through tight junctions to the
yolk syncytial layer (YSL), where directly adjacent to the EVL margin a contractile
actomyosin ring is formed that is thought to drive EVL epiboly. The prevalent
view in the field was that the contractile ring exerts a pulling force on the
EVL margin, which pulls the EVL towards the vegetal pole. However, how this force
is generated and how it affects EVL morphology still remains elusive. Moreover,
the cellular mechanisms mediating the increase in EVL surface area, while maintaining
tissue integrity and function are still unclear. Here we show that the YSL actomyosin
ring pulls on the EVL margin by two distinct force-generating mechanisms. One
mechanism is based on contraction of the ring around its circumference, as previously
proposed. The second mechanism is based on actomyosin retrogade flows, generating
force through resistance against the substrate. The latter can function at any
epiboly stage even in situations where the contraction-based mechanism is unproductive.
Additionally, we demonstrate that during epiboly the EVL is subjected to anisotropic
tension, which guides the orientation of EVL cell division along the main axis
(animal-vegetal) of tension. The influence of tension in cell division orientation
involves cell elongation and requires myosin-2 activity for proper spindle alignment.
Strikingly, we reveal that tension-oriented cell divisions release anisotropic
tension within the EVL and that in the absence of such divisions, EVL cells undergo
ectopic fusions. We conclude that forces applied to the EVL by the action of the
YSL actomyosin ring generate a tension anisotropy in the EVL that orients cell
divisions, which in turn limit tissue tension increase thereby facilitating tissue
spreading.

text: To fight infectious diseases, host immune defenses are employed at multiple
levels. Sanitary behavior, such as pathogen avoidance and removal, acts as a first
line of defense to prevent infection [1] before activation of the physiological
immune system. Insect societies have evolved a wide range of collective hygiene
measures and intensive health care toward pathogen-exposed group members [2].
One of the most common behaviors is allogrooming, in which nestmates remove infectious
particles from the body surfaces of exposed individuals [3]. Here we show that,
in invasive garden ants, grooming of fungus-exposed brood is effective beyond
the sheer mechanical removal of fungal conidiospores; it also includes chemical
disinfection through the application of poison produced by the ants themselves.
Formic acid is the main active component of the poison. It inhibits fungal growth
of conidiospores remaining on the brood surface after grooming and also those
collected in the mouth of the grooming ant. This dual function is achieved by
uptake of the poison droplet into the mouth through acidopore self-grooming and
subsequent application onto the infectious brood via brood grooming. This extraordinary
behavior extends the current understanding of grooming and the establishment of
social immunity in insect societies.

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.

text: Differential cell adhesion and cortex tension are thought to drive cell sorting
by controlling cell-cell contact formation. Here, we show that cell adhesion and
cortex tension have different mechanical functions in controlling progenitor cell-cell
contact formation and sorting during zebrafish gastrulation. Cortex tension controls
cell-cell contact expansion by modulating interfacial tension at the contact.
By contrast, adhesion has little direct function in contact expansion, but instead
is needed to mechanically couple the cortices of adhering cells at their contacts,
allowing cortex tension to control contact expansion. The coupling function of
adhesion is mediated by E-cadherin and limited by the mechanical anchoring of
E-cadherin to the cortex. Thus, cell adhesion provides the mechanical scaffold
for cell cortex tension to drive cell sorting during gastrulation.

text: Body axis elongation represents a common and fundamental morphogenetic process
in development. A key mechanism triggering body axis elongation without additional
growth is convergent extension (CE), whereby a tissue undergoes simultaneous narrowing
and extension. Both collective cell migration and cell intercalation are thought
to drive CE and are used to different degrees in various species as they elongate
their body axis. Here, we provide an overview of CE as a general strategy for
body axis elongation and discuss conserved and divergent mechanisms underlying
CE among different species.

text: How cells orchestrate their behavior during collective migration is a long-standing
question. Using magnetic tweezers to apply mechanical stimuli to Xenopus mesendoderm
cells, Weber etal. (2012) now reveal, in this issue of Developmental Cell, a cadherin-mediated
mechanosensitive response that promotes cell polarization and movement persistence
during the collective mesendoderm migration in gastrulation.

text: Visualizing and analyzing shape changes at various scales, ranging from single
molecules to whole organisms, are essential for understanding complex morphogenetic
processes, such as early embryonic development. Embryo morphogenesis relies on
the interplay between different tissues, the properties of which are again determined
by the interaction between their constituent cells. Cell interactions, on the
other hand, are controlled by various molecules, such as signaling and adhesion
molecules, which in order to exert their functions need to be spatiotemporally
organized within and between the interacting cells. In this review, we will focus
on the role of cell adhesion functioning at different scales to organize cell,
tissue and embryo morphogenesis. We will specifically ask how the subcellular
distribution of adhesion molecules controls the formation of cell-cell contacts,
how cell-cell contacts determine tissue shape, and how tissue interactions regulate
embryo morphogenesis.

text: 'The zonula adherens (ZA) of epithelial cells is a site of cell-cell adhesion
where cellular forces are exerted and resisted. Increasing evidence indicates
that E-cadherin adhesion molecules at the ZA serve to sense force applied on the
junctions and coordinate cytoskeletal responses to those forces. Efforts to understand
the role that cadherins play in mechanotransduction have been limited by the lack
of assays to measure the impact of forces on the ZA. In this study we used 4D
imaging of GFP-tagged E-cadherin to analyse the movement of the ZA. Junctions
in confluent epithelial monolayers displayed prominent movements oriented orthogonal
(perpendicular) to the ZA itself. Two components were identified in these movements:
a relatively slow unidirectional (translational) component that could be readily
fitted by least-squares regression analysis, upon which were superimposed more
rapid oscillatory movements. Myosin IIB was a dominant factor responsible for
driving the unilateral translational movements. In contrast, frequency spectrum
analysis revealed that depletion of Myosin IIA increased the power of the oscillatory
movements. This implies that Myosin IIA may serve to dampen oscillatory movements
of the ZA. This extends our recent analysis of Myosin II at the ZA to demonstrate
that Myosin IIA and Myosin IIB make distinct contributions to junctional movement
at the ZA.'

text: 'Diffusing membrane constituents are constantly exposed to a variety of forces
that influence their stochastic path. Single molecule experiments allow for resolving
trajectories at extremely high spatial and temporal accuracy, thereby offering
insights into en route interactions of the tracer. In this review we discuss approaches
to derive information about the underlying processes, based on single molecule
tracking experiments. In particular, we focus on a new versatile way to analyze
single molecule diffusion in the absence of a full analytical treatment. The method
is based on comprehensive comparison of an experimental data set against the hypothetical
outcome of multiple experiments performed on the computer. Since Monte Carlo simulations
can be easily and rapidly performed even on state-of-the-art PCs, our method provides
a simple way for testing various - even complicated - diffusion models. We describe
the new method in detail, and show the applicability on two specific examples:
firstly, kinetic rate constants can be derived for the transient interaction of
mobile membrane proteins; secondly, residence time and corral size can be extracted
for confined diffusion.'

text: Tissue surface tension (TST) is an important mechanical property influencing
cell sorting and tissue envelopment. The study by Manning et al. (1) reported
on a mathematical model describing TST on the basis of the balance between adhesive
and tensile properties of the constituent cells. The model predicts that, in high-adhesion
cell aggregates, surface cells will be stretched to maintain the same area of
cell–cell contact as interior bulk cells, resulting in an elongated and flattened
cell shape. The authors (1) observed flat and elongated cells at the surface of
high-adhesion zebrafish germ-layer explants, which they argue are undifferentiated
stretched germ-layer progenitor cells, and they use this observation as a validation
of their model.

text: Facial branchiomotor neurons (FBMNs) in zebrafish and mouse embryonic hindbrain
undergo a characteristic tangential migration from rhombomere (r) 4, where they
are born, to r6/7. Cohesion among neuroepithelial cells (NCs) has been suggested
to function in FBMN migration by inhibiting FBMNs positioned in the basal neuroepithelium
such that they move apically between NCs towards the midline of the neuroepithelium
instead of tangentially along the basal side of the neuroepithelium towards r6/7.
However, direct experimental evaluation of this hypothesis is still lacking. Here,
we have used a combination of biophysical cell adhesion measurements and high-resolution
time-lapse microscopy to determine the role of NC cohesion in FBMN migration.
We show that reducing NC cohesion by interfering with Cadherin 2 (Cdh2) activity
results in FBMNs positioned at the basal side of the neuroepithelium moving apically
towards the neural tube midline instead of tangentially towards r6/7. In embryos
with strongly reduced NC cohesion, ectopic apical FBMN movement frequently results
in fusion of the bilateral FBMN clusters over the apical midline of the neural
tube. By contrast, reducing cohesion among FBMNs by interfering with Contactin
2 (Cntn2) expression in these cells has little effect on apical FBMN movement,
but reduces the fusion of the bilateral FBMN clusters in embryos with strongly
diminished NC cohesion. These data provide direct experimental evidence that NC
cohesion functions in tangential FBMN migration by restricting their apical movement.

text: Recent advances in microscopy techniques and biophysical measurements have
provided novel insight into the molecular, cellular and biophysical basis of cell
adhesion. However, comparably little is known about a core element of cell–cell
adhesion—the energy of adhesion at the cell–cell contact. In this review, we discuss
approaches to understand the nature and regulation of adhesion energy, and propose
strategies to determine adhesion energy between cells in vitro and in vivo.

text: The process of gastrulation is highly conserved across vertebrates on both
the genetic and morphological levels, despite great variety in embryonic shape
and speed of development. This mechanism spatially separates the germ layers and
establishes the organizational foundation for future development. Mesodermal identity
is specified in a superficial layer of cells, the epiblast, where cells maintain
an epithelioid morphology. These cells involute to join the deeper hypoblast layer
where they adopt a migratory, mesenchymal morphology. Expression of a cascade
of related transcription factors orchestrates the parallel genetic transition
from primitive to mature mesoderm. Although the early and late stages of this
process are increasingly well understood, the transition between them has remained
largely mysterious. We present here the first high resolution in vivo observations
of the blebby transitional morphology of involuting mesodermal cells in a vertebrate
embryo. We further demonstrate that the zebrafish spadetail mutation creates a
reversible block in the maturation program, stalling cells in the transition state.
This mutation creates an ideal system for dissecting the specific properties of
cells undergoing the morphological transition of maturing mesoderm, as we demonstrate
with a direct measurement of cell–cell adhesion.

text: During the development of multicellular organisms, cell fate specification
is followed by the sorting of different cell types into distinct domains from
where the different tissues and organs are formed. Cell sorting involves both
the segregation of a mixed population of cells with different fates and properties
into distinct domains, and the active maintenance of their segregated state. Because
of its biological importance and apparent resemblance to fluid segregation in
physics, cell sorting was extensively studied by both biologists and physicists
over the last decades. Different theories were developed that try to explain cell
sorting on the basis of the physical properties of the constituent cells. However,
only recently the molecular and cellular mechanisms that control the physical
properties driving cell sorting, have begun to be unraveled. In this review, we
will provide an overview of different cell-sorting processes in development and
discuss how these processes can be explained by the different sorting theories,
and how these theories in turn can be connected to the molecular and cellular
mechanisms driving these processes.

text: The use of optical traps to measure or apply forces on the molecular level
requires a precise knowledge of the trapping force field. Close to the trap center,
this field is typically approximated as linear in the displacement of the trapped
microsphere. However, applications demanding high forces at low laser intensities
can probe the light-microsphere interaction beyond the linear regime. Here, we
measured the full nonlinear force and displacement response of an optical trap
in two dimensions using a dual-beam optical trap setup with back-focal-plane photodetection.
We observed a substantial stiffening of the trap beyond the linear regime that
depends on microsphere size, in agreement with Mie theory calculations. Surprisingly,
we found that the linear detection range for forces exceeds the one for displacement
by far. Our approach allows for a complete calibration of an optical trap.

text: Cell shape and motility are primarily controlled by cellular mechanics. The
attachment of the plasma membrane to the underlying actomyosin cortex has been
proposed to be important for cellular processes involving membrane deformation.
However, little is known about the actual function of membrane-to-cortex attachment
(MCA) in cell protrusion formation and migration, in particular in the context
of the developing embryo. Here, we use a multidisciplinary approach to study MCA
in zebrafish mesoderm and endoderm (mesendoderm) germ layer progenitor cells,
which migrate using a combination of different protrusion types, namely, lamellipodia,
filopodia, and blebs, during zebrafish gastrulation. By interfering with the activity
of molecules linking the cortex to the membrane and measuring resulting changes
in MCA by atomic force microscopy, we show that reducing MCA in mesendoderm progenitors
increases the proportion of cellular blebs and reduces the directionality of cell
migration. We propose that MCA is a key parameter controlling the relative proportions
of different cell protrusion types in mesendoderm progenitors, and thus is key
in controlling directed migration during gastrulation.

text: 'The development of multicellular organisms is dependent on the tight coordination
between tissue growth and morphogenesis. The stereotypical orientation of cell
divisions has been proposed to be a fundamental mechanism by which proliferating
and growing tissues take shape. However, the actual contribution of stereotypical
division orientation (SDO) to tissue morphogenesis is unclear. In zebrafish, cell
divisions with stereotypical orientation have been implicated in both body-axis
elongation and neural rod formation [1, 2], although there is little direct evidence
for a critical function of SDO in either of these processes. Here we show that
SDO is required for formation of the neural rod midline during neurulation but
dispensable for elongation of the body axis during gastrulation. Our data indicate
that SDO during both gastrulation and neurulation is dependent on the noncanonical
Wnt receptor Frizzled 7 (Fz7) and that interfering with cell division orientation
leads to severe defects in neural rod midline formation but not body-axis elongation.
These findings suggest a novel function for Fz7-controlled cell division orientation
in neural rod midline formation during neurulation. '

text: Cell sorting is a widespread phenomenon pivotal to the early development of
multicellular organisms. In vitro cell sorting studies have been instrumental
in revealing the cellular properties driving this process. However, these studies
have as yet been limited to two-dimensional analysis of three-dimensional cell
sorting events. Here we describe a method to record the sorting of primary zebrafish
ectoderm and mesoderm germ layer progenitor cells in three dimensions over time,
and quantitatively analyze their sorting behavior using an order parameter related
to heterotypic interface length. We investigate the cell population size dependence
of sorted aggregates and find that the germ layer progenitor cells engulfed in
the final configuration display a relationship between total interfacial length
and system size according to a simple geometrical argument, subject to a finite-size
effect.

text: Integrin- and cadherin-mediated adhesion is central for cell and tissue morphogenesis,
allowing cells and tissues to change shape without loosing integrity. Studies
predominantly in cell culture showed that mechanosensation through adhesion structures
is achieved by force-mediated modulation of their molecular composition. The specific
molecular composition of adhesion sites in turn determines their signalling activity
and dynamic reorganization. Here, we will review how adhesion sites respond to
mecanical stimuli, and how spatially and temporally regulated signalling from
different adhesion sites controls cell migration and tissue morphogenesis.
