text: Zygotic genome activation (ZGA) initiates regionalized transcription underlying
distinct cellular identities. ZGA is dependent upon dynamic chromatin architecture
sculpted by conserved DNA-binding proteins. However, the direct mechanistic link
between the onset of ZGA and the tissue-specific transcription remains unclear.
Here, we have addressed the involvement of chromatin organizer Satb2 in orchestrating
both processes during zebrafish embryogenesis. Integrative analysis of transcriptome,
genome-wide occupancy and chromatin accessibility reveals contrasting molecular
activities of maternally deposited and zygotically synthesized Satb2. Maternal
Satb2 prevents premature transcription of zygotic genes by influencing the interplay
between the pluripotency factors. By contrast, zygotic Satb2 activates transcription
of the same group of genes during neural crest development and organogenesis.
Thus, our comparative analysis of maternal versus zygotic function of Satb2 underscores
how these antithetical activities are temporally coordinated and functionally
implemented highlighting the evolutionary implications of the biphasic and bimodal
regulation of landmark developmental transitions by a single determinant.

text: Non-canonical Wnt signaling plays a central role for coordinated cell polarization
and directed migration in metazoan development. While spatiotemporally restricted
activation of non-canonical Wnt-signaling drives cell polarization in epithelial
tissues, it remains unclear whether such instructive activity is also critical
for directed mesenchymal cell migration. Here, we developed a light-activated
version of the non-canonical Wnt receptor Frizzled 7 (Fz7) to analyze how restricted
activation of non-canonical Wnt signaling affects directed anterior axial mesendoderm
(prechordal plate, ppl) cell migration within the zebrafish gastrula. We found
that Fz7 signaling is required for ppl cell protrusion formation and migration
and that spatiotemporally restricted ectopic activation is capable of redirecting
their migration. Finally, we show that uniform activation of Fz7 signaling in
ppl cells fully rescues defective directed cell migration in fz7 mutant embryos.
Together, our findings reveal that in contrast to the situation in epithelial
cells, non-canonical Wnt signaling functions permissively rather than instructively
in directed mesenchymal cell migration during gastrulation.

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: 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: 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: '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.'
