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.
