This lesson examines a process in early development that is common to many organisms, where cells adopt certain roles and migrate to appropriate locations in the embryo in order to fulfill those roles. This lesson is 51 pages long, and in addition to text contains 15 high resolution images and figures, 4 movies, 6 simulations, 18 fragments of simulation code, and 17 review questions.
This lesson requires the ACSE Software, QuickTime, and a color Macintosh with a hard disk and at least 8 MB of memory.

This lesson examines the way that gradients of molecules produced by the mother and stored within the unfertilized egg can result in differences among embryonic cells and the generation of patterns in the organism.
