[Incorporation of 3H-uridine into the large decidual cells of rats and their differentiation].
The antimesometrial part of rat's decidua of the 9th day of gestation was divided into three zones. Cells of either zone display their own morphological and cytochemical properties. Different rates of 3H-uridine incorporation were observed in the cytoplasm and the nucleus in cells of either zone during 5, 30, 60 and 240 minutes after precursor injection. The largest member of silver grain accumulation was observed in the karyoplasm and nucleolus of cells of the transitional zone. The nucleus of basal zone cells had the smallest intensity of 3H-uridine incorporation. The nuclei of the epithelial zone cells are characterized by a lower intensity of 3H-uridine incorporation than those of the transition zone. The intensity to cytoplasmic accumulation of silver grains raised from cells of the basal zone up to cells of the epithelial zone. The largest quantity of cytoplasmic radioactivity was observed 240 minutes after 3H-uridine injection.
