[Early postnatal proliferation of the retinal pigment epithelium cells in the mouse].
A burst of proliferative activity with a maximum of DNA-synthesizing cells on the first day after birth was found in the central zone of the retinal pigment epithelium (RPE) in albino mice from the moment of birth to 9 days of life using radioautography with 3H-thymidine pulse labelling. During this period the central RPE zone, which consists in newborns of mononuclear cells by 95%, gradually transforms in a population with predominance of binuclear cells and fluctuations in the index of labelled nuclei (after the kinetics of cell population in the central RPE zone is similar in mice and rats both in accumulation of binuclear cells and fluctuations in the index of labelled nuclei (after pulse labelling), except that in mice the peak of the index of labelled nuclei is observed earlier than in rats.
