a study of the development of eye retina in sturgeons ( acipenser guldenstadti and a. stellatus ) by means of autoradiography has shown that during embryogenesis the cells of the high light sensitivity region complete the cycle of proliferation prior to the stage 29 , what corresponds to the completion of proliferation of the retina cells in anurans and mammals , rather than at the stage 33 , as was considered previously on the basis of the light microscopy morphological studies of differentiation .
