[Potential transformation of the anterior corneal epithelium of the common frog]

The possibility of transformation of the corneal anterior epithelium in the lens following its separation from the stroma was studied. The corneal epithelium was implanted into: a) empty eye orbit and b) cavity of lensless eye of the Rana temporaria tadpoles. In the eye orbit it continued, as in the normal development, to form the basal membrane. Although in the eye cavity the structures similar to lentoids arose but the specific lens proteins were shown to be asbent from them using immunofluorescence. In both the cases, thus, no transformation of the corneal epithelium in the lens was observed. The role of stroma in the stabilization of differentiation of the corneal anterior epithelium is discussed. It is suggested that the absence of increase in the mitotic activity is one of the causes of failure of the corneal epithelium transformation in the lens.
