Fig. 3From: Allopregnanolone alters follicular and luteal dynamics during the estrous cycleEffect of ALLO on the proliferation index (PCNA positive immunostained cells over the total number of cells) in follicles (a) and corpora lutea (b). Control groups follicles (a upper panel), ALLO treated follicles (a lower panel), control groups CL (b upper panel), ALLO treated groups CL (b lower panel); E, D1, D2, PE from left to right. Representative photomicrographs of follicles and corpora lutea immunostained for PCNA at each stage of the estrous cycle. Black arrow indicate proliferating endothelial cells, red arrow indicate proliferating small luteal cells. Values are expressed as mean ± S.E.M. Two-way ANOVA followed by Bonferroni’s post hoc, (n=6), *p<0.05, ***p<0.001. Magnification: follicles 200x, CL 400xBack to article page
