Respecification of vertebral identities by retinoic acid.

Abstract excerpt

In higher vertebrates, the formation of the body axis proceeds in a craniocaudal direction during gastrulation. Cell biological evidence suggests that mesoderm formation and specification of axial positions occur simultaneously. Exposure of gastrulating embryos to retinoic acid induces changes in axial patterns, e.g. anterior and posterior homeotic transformations of vertebrae. These morphological changes are...
