Induction of tooth and eye by transplantation of activin A-treated, undifferentiated presumptive ectodermal Xenopus cells into the abdomen.

Abstract excerpt

Activin A can induce the Xenopus presumptive ectoderm (animal cap) to form different types of mesoderm and endoderm at different concentrations and the animal cap treated with activin can function as an organizer during early development. The dissociated Xenopus animal cap cells treated with activin form an aggregate and it develops into various tissues in vitro. In this study, to induce jaw cartilage from...
