Histological sections of the ovaries on the 21st day of experiment. (a), (b) After saline administration: Primordial and primary follicles were not available; the extensive area of ovaries was filled with stroma (S) in which the full-blooded capillaries (1) and hemorrhages (2) were determined. Granulosa cells (3) were compressed, separated, and were less adjacent to oocyte (O). (c), (d) After cMSC administration: The follicular profile was characterized by the presence of primordial (4), primary (5), and preantral (6) follicles. Hematoxylin and eosin staining.
