text: During embryonic development, mechanical forces are essential for cellular
rearrangements driving tissue morphogenesis. Here, we show that in the early zebrafish
embryo, friction forces are generated at the interface between anterior axial
mesoderm (prechordal plate, ppl) progenitors migrating towards the animal pole
and neurectoderm progenitors moving in the opposite direction towards the vegetal
pole of the embryo. These friction forces lead to global rearrangement of cells
within the neurectoderm and determine the position of the neural anlage. Using
a combination of experiments and simulations, we show that this process depends
on hydrodynamic coupling between neurectoderm and ppl as a result of E-cadherin-mediated
adhesion between those tissues. Our data thus establish the emergence of friction
forces at the interface between moving tissues as a critical force-generating
process shaping the embryo.

text: 'Actin and myosin assemble into a thin layer of a highly dynamic network underneath
the membrane of eukaryotic cells. This network generates the forces that drive
cell- and tissue-scale morphogenetic processes. The effective material properties
of this active network determine large-scale deformations and other morphogenetic
events. For example, the characteristic time of stress relaxation (the Maxwell
time τM) in the actomyosin sets the timescale of large-scale deformation of the
cortex. Similarly, the characteristic length of stress propagation (the hydrodynamic
length λ) sets the length scale of slow deformations, and a large hydrodynamic
length is a prerequisite for long-ranged cortical flows. Here we introduce a method
to determine physical parameters of the actomyosin cortical layer in vivo directly
from laser ablation experiments. For this we investigate the cortical response
to laser ablation in the one-cell-stage Caenorhabditis elegans embryo and in the
gastrulating zebrafish embryo. These responses can be interpreted using a coarse-grained
physical description of the cortex in terms of a two-dimensional thin film of
an active viscoelastic gel. To determine the Maxwell time τM, the hydrodynamic
length λ, the ratio of active stress ζΔμ, and per-area friction γ, we evaluated
the response to laser ablation in two different ways: by quantifying flow and
density fields as a function of space and time, and by determining the time evolution
of the shape of the ablated region. Importantly, both methods provide best-fit
physical parameters that are in close agreement with each other and that are similar
to previous estimates in the two systems. Our method provides an accurate and
robust means for measuring physical parameters of the actomyosin cortical layer.
It can be useful for investigations of actomyosin mechanics at the cellular-scale,
but also for providing insights into the active mechanics processes that govern
tissue-scale morphogenesis.'

text: 'Vertebrates have a unique 3D body shape in which correct tissue and organ
shape and alignment are essential for function. For example, vision requires the
lens to be centred in the eye cup which must in turn be correctly positioned in
the head. Tissue morphogenesis depends on force generation, force transmission
through the tissue, and response of tissues and extracellular matrix to force.
Although a century ago D''Arcy Thompson postulated that terrestrial animal body
shapes are conditioned by gravity, there has been no animal model directly demonstrating
how the aforementioned mechano-morphogenetic processes are coordinated to generate
a body shape that withstands gravity. Here we report a unique medaka fish (Oryzias
latipes) mutant, hirame (hir), which is sensitive to deformation by gravity. hir
embryos display a markedly flattened body caused by mutation of YAP, a nuclear
executor of Hippo signalling that regulates organ size. We show that actomyosin-mediated
tissue tension is reduced in hir embryos, leading to tissue flattening and tissue
misalignment, both of which contribute to body flattening. By analysing YAP function
in 3D spheroids of human cells, we identify the Rho GTPase activating protein
ARHGAP18 as an effector of YAP in controlling tissue tension. Together, these
findings reveal a previously unrecognised function of YAP in regulating tissue
shape and alignment required for proper 3D body shape. Understanding this morphogenetic
function of YAP could facilitate the use of embryonic stem cells to generate complex
organs requiring correct alignment of multiple tissues. '

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: 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: 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: 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: 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: 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: 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: 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.
