Pituitary melanotrope cells of Xenopus laevis are of neural ridge origin and do not require induction by the infundibulum

Highlights ► This study followed early pituitary development in Xenopus laevis . ► Extirpation and grafting studies investigated the role(s) of the brain upon melanotrope differentiation. ► Removal of the presumptive suprachiasmatic area enhanced melanotrope differentiation. ► The infundibulum is no...

Summary:Highlights ► This study followed early pituitary development in Xenopus laevis . ► Extirpation and grafting studies investigated the role(s) of the brain upon melanotrope differentiation. ► Removal of the presumptive suprachiasmatic area enhanced melanotrope differentiation. ► The infundibulum is not a pituitary inductor.
