Effect of Phorbol Esters on the Regulation of Rat Decidual Cell RegressionSpecific Aims: 1. To determine the decidual stromal cell cycle by analysis of mitotic figures, PCNA expression and flow cytometry and examine its correlation with PKC enzyme activity in stromal cells at 8, 10, 12, 14, and 17 days of pregnancy. 2. To determine the changes induced by the administration of phorbol esters on mitotic figures, PCNA expression, flow cytometry and PKC enzyme activity in stromal cells and examine the correlation between cell cycle changes with PKC enzyme activity. 3. To determine the effects of phorbol esters on ER and PR mRNAs and progesterone binding sites at day 10 and day 14 of pregnancy, the time of decidual stromal cell proliferation and regression respectively. 4. To determine the effect of antiprogestin (RU 486) on PKC enxyme activity in stromal cells at day 10 of pregnancy.
