In chordates in general and in Xenopus in particular, the animal’s body axis is organized largely as a dorsal collinear array of notochord, nerve cord, and somites, divided antero-posteriorly into head, trunk, and tail. Ventral aspects of the body axis are less obvious than dorsal, but include an antero-posterior ordering of branchial and gut regions, and heart and blood islands. This organization arises at the gastrula stage of development, through the action of a small population of cells collectively called the “gastrula organizer” which we wish to discuss in terms of its formation and function.
