The Increased Expression of Connexin and VEGF in Mouse Ovarian Tissue Vitrification by Follicle Stimulating Hormone

Figure 1

Quantification of the normal follicle. Compared with the CG and NG-FSH groups, the morphological structure of the ovarian tissues in the OG-FSH group maintained its integrity, and the percentage of normal follicles was significantly higher compared to the other groups () (Figure 1). (a)–(e) Results of HE staining. (a) CG (fresh control group). (b) NG-FSH (no FSH was administered during ovarian vitrification). (c) OG-FSH (FSH was administered during ovarian vitrification). (d) EG-FSH (FSH was administered during the early process of ovarian vitrification). (e) LG-FSH (FSH was administered during the late process of ovarian vitrification). PF indicates primordial follicles; P indicates primary follicles; S indicates secondary follicles (S). (f) Quantification of normal ovarian follicles for the different groups. The different letters indicate a significant difference; the same letters indicate no difference.
