Gastrulation Movie

Gastrulation on Film!

If you have the QuickTime plug-in properly installed on your browser, you should see a black-and-white movie loading below, to the left of the caption. The file is fairly large and, depending on the speed of your connection, it may take anywhere from several seconds to several minutes to load. Once the transfer is complete, however, the movie will play automatically, showing you the process of gastrulation. You can use the controls at the bottom of the movie screen to view individual panels or to play through the full length again.

If you are having problems getting the movie to load, you may not have the QuickTime plug-in properly installed. Go to to get plug-in assistance and information.

Movie of Xenopus gastrulation made by Dr. M. Danilchik, Oregon Health Sciences University. A confocal microscope was used to make optical sections of embryos at different stages of gastrulation. Images of midsagittal sections of the various stages were then morphed into a movie. the animal pole is up, and dorsal is to the right. There is a lot going on, so watch one thing at a time, e.g., the blastocoel.
