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: 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: 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: 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.
