The rat retina has been a useful model system for the study of the development of the central nervous system (CNS). In order to facilitate future studies on the mechanisms that control retinal growth, we have quantified the proliferation of retinal cells and the length of the cell cycle throughout development. For each day during development, the number of mitotic and postmitotic cells per reti...
