Bidirectional redistribution of actomyosin drives epithelial invagination in ascidian siphon tube morphogenesis
How epithelia perform a spatiotemporal heterogeneous force-generating program to drive a sequential tissue morphogenesis remains unclear, particularly the underlying precise mechanical mechanisms. This study investigated dynamic actomyosin reorganization between apical and lateral membrane cortex regions during two sequentially invaginated stages of atrial siphon tube morphogenesis in the…
