Dorsal Closure Close-up (VIDEO) European Molecular Biology Laboratory This video is under embargo. Please login to access this video.

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.
