[Interkinetic migration of the auditory placode in the chick embryo]

Abstract

Interkinetic nuclear migration was studied in cells forming the auditory placode of chick embryos with thymidine H3 and autoradiography. Our results show, that the nuclei in the auditory placode, synthesize D.N.A. in the outer zone, then migrate toward the inner zone to undergo division and subsequently return to the outer zone.
