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."}],"acknowledgement":"We thank Carl Goodrich and the members of the Heisenberg and Hannezo groups, in particular Reka Korei, for help, technical advice, and discussions; and the Bioimaging and zebrafish facilities of the IST Austria for continuous support.

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.","lang":"eng"}],"external_id":{"pmid":["31512749"],"isi":["000485561900001"]},"project":[{"call_identifier":"H2020","_id":"260F1432-B435-11E9-9278-68D0E5697425","grant_number":"742573","name":"Interaction and feedback between cell mechanics and fate specification in vertebrate gastrulation"},{"_id":"2693FD8C-B435-11E9-9278-68D0E5697425","grant_number":"V00736","name":"Tissue material properties in embryonic development","call_identifier":"FWF"}],"publication_identifier":{"issn":["0261-4189"],"eissn":["1460-2075"]},"corr_author":"1","department":[{"_id":"CaHe"}],"title":"Tissue rheology in embryonic organization","oa_version":"Published Version","date_created":"2019-11-04T15:24:29Z","doi":"10.15252/embj.2019102497","article_processing_charge":"Yes (via OA deal)"}]
