Dorsal Closure Close-up

Caption: The pulsing amnioserosa cells (on the left) pull on the smaller neighboring epidermis cells. The result is a stepwise dorsal-ward (towards the left) displacement of the epidermis front. Displacement is sustained by the ratchet-like function of the actin cable that forms at the boundary between amnioserosa cells and epidermis. The movie was recorded with a standard spinning disc confocal microscope using 60x magnification.
