Abstract
Cell divisions can either promote or inhibit tissue morphogenesis. In contractile epithelia, mitotic entry disrupts medioapical myosin activation and reverses apical constriction. We found that different spatiotemporal patterns of mitotic entry and the resultant changes in force generation at the tissue level dictate distinct tissue shape outcomes.
