Avian scale development. V. Ultrastructure of the chorionic epithelium induced by anterior shank dermis from the scaleless mutant

Abstract

In combination with dermis from the anterior shank skin of the scaleless mutant, the chorionic epithelium forms an epidermis whose ultrastructural features are indistinguishable from those seen along the inner surface of normal scales and along the anterior shank of the scaleless mutant.
