Fig. 7From: The effect of human menstrual blood-derived stem cells on ovarian folliculogenesis, angiogenesis and collagen volume in female rats affected by the polycystic ovary syndromeHistopathological changes in the ovaries of the control and experimental groups. A) control group; B) sham group (CMC); C) PCOS group; D) PCOS-Sham group; E) PCOS+Stem cells group. The control group showed normal ovarian morphology, while the PCOS and PCOS-Sham groups showed the presence of many cysts (blue arrows). In the PCOS+Stem cells group, the ovarian structure seemed more similar to controls, with an increase in the number of follicles and a decrease in cysts.
