Myosin II regulates complex cellular arrangement and epithelial architecture in Drosophila.
Remodeling epithelia is a primary driver of morphogenesis. Here, we report a central role of myosin II in regulating several aspects of complex epithelial architecture in the Drosophila eye imaginal disc. The epithelial indentation of the morphogenetic furrow is established from a pattern of myosin II activation defined by the developmental signals Hedgehog and Decapentaplegic. More generally, patterned myosin activation can control diverse three-dimensional epithelial sculpting. We have deve...Expand abstract
