Hela cell stained for F-actin with phalloidin visualized with super resolution microcopy (Wu Yao). Each image in the series of four is an enlargement of the one above
During ventral enclosure epidermal cells wrap around the embryo from the dorsal side to meet at the ventral midline. In this movie hypodermal cells are expressing an actin binding GFP reporter.
Elongation involves dramatic cell shape change in all cells, including the hypodermal cells. Cell-cell junctions are highlighted in this movie of DLG-1::GFP
Gastrulation cleft closure is seen in this embryo, which is expressing a CED-10::GFP bound to all membranes.
Microtubule dynamics in a comma stage embryo can be appreciated in this 20 second interval movie of tubulin::GFP
GFP can also be expressed in the nuclei allowing the following of nuclear dynamics in developing embryos
