text: Embryo morphogenesis is impacted by dynamic changes in tissue material properties,
which have been proposed to occur via processes akin to phase transitions (PTs).
Here, we show that rigidity percolation provides a simple and robust theoretical
framework to predict material/structural PTs of embryonic tissues from local cell
connectivity. By using percolation theory, combined with directly monitoring dynamic
changes in tissue rheology and cell contact mechanics, we demonstrate that the
zebrafish blastoderm undergoes a genuine rigidity PT, brought about by a small
reduction in adhesion-dependent cell connectivity below a critical value. We quantitatively
predict and experimentally verify hallmarks of PTs, including power-law exponents
and associated discontinuities of macroscopic observables. Finally, we show that
this uniform PT depends on blastoderm cells undergoing meta-synchronous divisions
causing random and, consequently, uniform changes in cell connectivity. Collectively,
our theoretical and experimental findings reveal the structural basis of material
PTs in an organismal context.

text: Tissue morphogenesis in multicellular organisms is brought about by spatiotemporal
coordination of mechanical and chemical signals. Extensive work on how mechanical
forces together with the well‐established morphogen signalling pathways can actively
shape living tissues has revealed evolutionary conserved mechanochemical features
of embryonic development. More recently, attention has been drawn to the description
of tissue material properties and how they can influence certain morphogenetic
processes. Interestingly, besides the role of tissue material properties in determining
how much tissues deform in response to force application, there is increasing
theoretical and experimental evidence, suggesting that tissue material properties
can abruptly and drastically change in development. These changes resemble phase
transitions, pointing at the intriguing possibility that important morphogenetic
processes in development, such as symmetry breaking and self‐organization, might
be mediated by tissue phase transitions. In this review, we summarize recent findings
on the regulation and role of tissue material properties in the context of the
developing embryo. We posit that abrupt changes of tissue rheological properties
may have important implications in maintaining the balance between robustness
and adaptability during embryonic development.

text: Tissue morphogenesis is driven by mechanical forces that elicit changes in
cell size, shape and motion. The extent by which forces deform tissues critically
depends on the rheological properties of the recipient tissue. Yet, whether and
how dynamic changes in tissue rheology affect tissue morphogenesis and how they
are regulated within the developing organism remain unclear. Here, we show that
blastoderm spreading at the onset of zebrafish morphogenesis relies on a rapid,
pronounced and spatially patterned tissue fluidization. Blastoderm fluidization
is temporally controlled by mitotic cell rounding-dependent cell–cell contact
disassembly during the last rounds of cell cleavages. Moreover, fluidization is
spatially restricted to the central blastoderm by local activation of non-canonical
Wnt signalling within the blastoderm margin, increasing cell cohesion and thereby
counteracting the effect of mitotic rounding on contact disassembly. Overall,
our results identify a fluidity transition mediated by loss of cell cohesion as
a critical regulator of embryo morphogenesis.

text: The seminal observation that mechanical signals can elicit changes in biochemical
signalling within cells, a process commonly termed mechanosensation and mechanotransduction,
has revolutionized our understanding of the role of cell mechanics in various
fundamental biological processes, such as cell motility, adhesion, proliferation
and differentiation. In this Review, we will discuss how the interplay and feedback
between mechanical and biochemical signals control tissue morphogenesis and cell
fate specification in embryonic development.
