During gastrulation, cell movements result in a massive reorganization of the embryo from a simple spherical ball of cells, the blastula, into a multi-layered organism. In his second video, Harland simplifies this complex phase of frog development by breaking it down into 7 separate steps and describing the specific cell rearrangements associated with each step.

Early Frog Development: How to Make a Tadpole
Xenopus laevis, is an excellent model to study vertebrate development. Richard Harland outlines frog development including the cell movements and molecular signals of gastrulation. (Talk recorded in October 2017)
