Ovarian histopathology using HE staining (×20). In different types of follicles, the difference for the number of follicles among the control, POI, UCMSC-iv, and UCMSC-OI groups was analyzed. (a) Control group; (b) POI group; (c) UCMSC-iv group; (d) UCMSC-OI group; (e) counts of primordial follicle; (f) counts of primary follicle; (g) counts of secondary follicle; and (h) counts of antral follicle.
