Morphogenesis is the process of reshaping single-cell zygotes to the final form of a developed animal. Embryonic gene patterning systems determine the body axes and lay down the spatiotemporal specification coordinates for cells. Gene patterning systems also affect the organization of cytoskeletal components in order to drive tissue...

Cell apical constriction driven by actomyosin contraction forces is a conserved mechanism during tissue folding in embryo development. While much is now understood of the molecular mechanism responsible for apical constriction and of the tissue-scale integration of the ensuing in-plane deformations, it is still not clear if apical actomyosin...
