Cell Movements in Development

Here’s an amazing video of cell divisions and movements in early embryonic zebrafish development:

Mo writes about the video and the science behind it at The Neurophilosophy Blog:

This reconstruction, produced by researchers from the European Molecular Biology Laboratory in Heidelberg, Germany using a technique called digital scanned laser light sheet fluorescence microscopy, shows the movements of all 16,000 cells in an 18-hour-old zebrafish embryo.

To make the film, the researchers injected a fluorescent protein into an embryo at the one cell stage. They began imaging at the 64-cell stage and captured images every 90 seconds for 12 hours.

This movie and 15 others accompany a paper published in a recent issue of Science.
