Abstract:
Objective:To explore the therapeutic effects of bone marrow-derived mesenchymal stem cells (BMSCs) on premature ovarian failure (POF) in mice induced by cyclophosphamide (CTX) and the possible mechanisms.Methods:Mouse BMSCs were identified through detection of cell surface markers by flow cytometry.The model of mouse POF was induced by intraperitoneal injection of CTX at a dose of 50 mg/kg,once daily for 15 days.BMSCs were transplanted into POF mice at 2×106 cells/mouse by tail veil.The ovarian tissues were collected for HE staining at 7 days after transplantation to observe the changes of ovarian structure and real-time PCR was performed to detect the folliculogenesis gene expression.Results:BMSCs showed positive expression of CD29 and CD90 while low expression for endothelial and hematopoietic cell markers CD31 and CD34.The numbers of primodial follicle,primary follicle,secondary follicle and antral follicle were significantly decreased,but the numbers of atretic follicle were significantly increased in CTX induced-POF mice (P＜0.05).BMSCs transplantation effectively repaired the structure of damaged ovary.The significant reduction of atretic follicle and significant increase of antral follicle and secondary follicle were observed in ovaries of BMSCs-treated mouse(P＜0.05).BMSCs-transplanted mouse ovaries showed the increased mRNA expression levels ofNano3,Nobox,and Lhx8 (P＜0.05).Conclusion:BMSCs could effectively repair ovarian structure and promote follicle development in CTX-induced POF mouse.
