Fig. 2From: Human amniotic mesenchymal stem cells improve the follicular microenvironment to recover ovarian function in premature ovarian failure miceThe transplanted hAMSCs improve oestrus cycles in POF mice. Vaginal smears were obtained, and the oestrus cycles were evaluated by H&E staining. Representative photographs for proestrus (a), oestrus (b), metoestrus (c), and dioestrus (d) are shown (× 100). e The percentage of abnormal cyclicity was detected in mice at 7 and 14 days after cells transplantation (n = 6)Back to article page
