[Proliferation of the cells of iris and pigment epithelium of the retina in the early periods after removal of the lens and iris in Spanish newts].

It has been shown by means of autoradiography that following the simultaneous removal of lens and retina in the eyes of adult ribbed newts (Pleurodeles waltlii) the proliferative processes related to the regeneration of retina, rather than lens, are most active at the early stages of eye restoration. During the lens regeneration in the absence of retina, the proliferation of the cells of pars iridica of the dorsal iris zone, a source of lens regeneration, is delayed, possibly due to the increase of the duration of mitotic cycle of these cells.
