Fig. 3From: Human endometrial mesenchymal stem cells restore ovarian function through improving the renewal of germline stem cells in a mouse model of premature ovarian failureVaginal exfoliative cell smear and cervical mucus crystallization indicating estrous cycles of mice in different groups and at different observed time points. At 2, 4, and 8Â weeks after cell transplantation, the typical cornified epithelial (black arrow) and typical ferning patterns (white arrow) were observed in EnSCs-treated mice, whereas cyclicity in Chemoablated animals remained unchangedBack to article page
