Abstract BackgroundAt present, there is no effective treatment for premature ovarian failure (POF), and stem cell therapy is considered the most promising treatment. Human umbilical cord blood mesenchymal stem cells (hUC-MSCs) have shown good regenerative ability in a variety of diseases including POI, but the method and dosage of hUC-MSCs to treat POI are not clear. This study aims to explore the treatment options of hUC-MSCs for POF by comparing single injection and multiple injections of hUC-MSCs on the ovarian function repair of POF caused by chemotherapy drugs.MethodsFemale mice were injected intraperitoneally with 30 mg/kg of busulfan and 120 mg/kg of cyclophosphamide to induce POF. In the single hUC-MSCs injection group, 7 days after the mice were injected with cyclophosphamide and busulfan, hUC-MSCs were transplanted into these mice. In the multiple injection group, hUC-MSCs were transplanted 7 days, 14 days and 21 days after the mice were injected with cyclophosphamide and busulfan. We evaluated ovarian morphology, fertility, follicle stimulating hormone and estradiol concentration, and follicle count, evaluated POF model and cell transplantation. In addition, real-time PCR, immunohistochemistry, miRNA chip and mRNA chip are used to evaluate the effect of cell therapy.ResultsCompared with the POF group, the ovarian size and primordial follicle count in the hUC-MSC group were significantly improved, and the fertility was also significantly improved. Immunohistochemistry showed that compared with the POF group, the anti-Mullerian hormone and Ki-67 in the ovary of the hUC-MSC group increased significantly, and ovulation was significantly restored. Real-time PCR showed that the expression of follicle stimulating hormone receptor, inhibin and inhibin in the hUC-MSCs group was significantly restored compared with the POF group. The results of mRNA and miRNA chips also showed that hUC-MSC restored ovarian function at the gene level. long-term treatment effect shows that the multiple transplantation hUC-MSCs group is better than the single transplantation hUC-MSCs group. 60 days after the mice were injected with cyclophosphamide and busulfan, the organ coefficient of multiple transplantation of hUC-MSCs increased compared with the POF group, the number of primary follicles increased, and hormone secretion increased. ConclusionThe results show that multiple trasplantation of hUC-MSCs can promote the recovery of ovarian function in POF mice more than a single transplantation. This study provides a basis for the therapeutic dose and therapeutic effect of hUC-MSCs on POF.

With the development of regenerative medicine, stem cells are being considered more frequently for the treatment of reproductive aging. Human umbilical cord mesenchymal stem cells have been reported to improve the reserve function of aging ovaries through their homing and paracrine effects. In this process, paracrine factors secreted by stem cells play an important role in ovarian recovery. Although the transplantation of human umbilical cord mesenchymal stem cells to improve ovarian function has been studied with great success in animal models of reproductive aging, their application in clinical research and therapy is still relatively rare. Therefore, this paper reviews the role of human umbilical cord mesenchymal stem cells in the treatment of reproductive aging and their related mechanisms, and it does so in order to provide a theoretical basis for further research and clinical treatment.

Premature ovarian failure (POF) is one of the most common causes of infertility in women. In our present study, we established cyclophosphamide- (CTX-) induced POF rat model and elucidated its effect on ovarian function. We detected the serum estrogen, follicle stimulating hormone, and anti-Müllerian hormone of mice models by ELISA and evaluated their folliculogenesis by histopathology examination. Our study revealed that CTX administration could severely disturb hormone secretion and influence folliculogenesis in rat. This study also detected ovarian cells apoptosis by deoxy-UTP-digoxigenin nick end labeling (TUNEL) and demonstrated marked ovarian cells apoptosis in rat models following CTX administration. In order to explore the potential of human umbilical cord mesenchymal stem cells (UCMSCs) in POF treatment, the above indexes were used to evaluate ovarian function. We found that human UCMSCs transplantation recovered disturbed hormone secretion and folliculogenesis in POF rat, in addition to reduced ovarian cell apoptosis. We also tracked transplanted UCMSCs in ovaries by fluorescencein situhybridization (FISH). The results manifested that the transplanted human UCMSCs could reside in ovarian tissues and could survive for a comparatively long time without obvious proliferation. Our present study provides new insights into the great clinical potential of human UCMSCs in POF treatment.

Abstract Background Premature ovarian insufficiency (POI) is an ovarian dysfunction that seriously affects a woman’s physiological health and reproduction. Mesenchymal stem cell (MSC) transplantation offers a promising treatment option for ovarian restoration in rodent POI models. However, the efficacy and mechanism of it remain unclear. Methods POI mice model was generated by cyclophosphamide and busulfan, followed with the treatment of tail-vein injection of the human umbilical cord mesenchymal stem cells (hUCMSCs). Maternal physiological changes and offspring behavior were detected. To reveal the pathogenesis and therapeutic mechanisms of POI, we first compared the metabolite profiles of healthy and POI ovarian tissues using untargeted metabolomics analyses. After stem cell therapy, we then collected the ovaries from control, POI, and hUCMSC-treated POI groups for lipid metabolomics and pseudotargeted metabolomics analysis. Results Our results revealed remarkable changes of multiple metabolites, especially lipids, in ovarian tissues after POI generation. Following the transplantation of clinical-grade hUCMSCs, POI mice exhibited significant improvements in body weight, sex hormone levels, estrous cycles, and reproductive capacity. Lipid metabolomics and pseudotargeted metabolomics analyses for the ovaries showed that the metabolite levels in the POI group, mainly lipids, glycerophospholipids, steroids, and amino acids changed significantly compared with the controls’, and most of them returned to near-healthy levels after receiving hUCMSC treatment. Meanwhile, we also observed an increase of monosaccharide levels in the ovaries from POI mice and a decrease after stem cell treatment. Conclusions hUCMSCs restore ovarian function through activating the PI3K pathway by promoting the level of free amino acids, consequently improving lipid metabolism and reducing the concentration of monosaccharides. These findings provide potential targets for the clinical diagnosis and treatment of POI.

Abstract Background: Previous studies have reported that transplantation of mesenchymal stem cells (MSCs) from many human tissues can improve ovarian dysfunction. However, the therapeutic effects of single injection of MSCs and multiple injections of MSCs on premature ovarian failure (POF) have not been reported yet. In this study, we used long-term follow-up to study the effect of human umbilical cord mesenchymal stem cell (hUC-MSCs) on the functional recovery of mouse POF models. Methods: In this study, we used a mouse model of premature ovarian failure induced by the combination of 120mg/kg cyclophosphamide and 30mg/kg busulfan. Enzyme-linked immunosorbent assay (ELISA) was used to detect estradiol (E2) and follicle stimulating hormone (FSH) levels in mouse serum. Evaluate ovarian function by counting follicles, ovarian weight, number of proliferating cells, anti-Mullerian hormone (AMH) and oocytes. Results: Our study shows that hUC-MSCs have obvious therapeutic effect for the POF mice model, and treatment effect of multiple transplantation is better than single transplantation. Mesenchymal stem cells were detected in follicular granulosa cells with tracer of the ovarian tissue freezing slice, which show hUC-MSCs to selectively migration and stay in damaged tissues. Genome Array screened a number of differentially expressed genes, the hUC-MSCs can change the level of expression of certain genes in the ovarian tissue, thus affecting ovarian function, and laid the foundation for us to further explore the mechanism of hUC-MSCs treatment of premature ovarian failure. Conclusion: This study demonstrated that hUC-MSCs transplantation significantly restored ovarian function after chemotherapy-induced damage.

Abstract Background Currently, there is no effective treatment for premature ovarian failure (POF), and stem cell therapy is considered the most promising treatment. Human umbilical cord blood mesenchymal stem cells (hUC-MSCs) have shown good regenerative ability in various diseases, including POF; however, their underlying mechanism and dosage for POF treatment remain unclear. This study aimed to compare the effect of single and multiple injections of hUC-MSCs on ovarian function repair in chemotherapy-induced POF. Methods Female mice were intraperitoneally injected with 30 mg/kg busulfan and 120 mg/kg cyclophosphamide (CTX) to induce POF. In the single hUC-MSC injection group, hUC-MSCs were transplanted into mice D7 after CTX and busulfan administration, while in the multiple injection group, hUC-MSCs were transplanted on D7, D14, and D21 after CTX and busulfan administration. We evaluated the ovarian morphology, fertility, follicle-stimulating hormone and estradiol concentrations, follicle count, POF model, and cell transplantation results. In addition, real-time polymerase chain reaction, immunohistochemistry, and miRNA and mRNA chips were used to evaluate the effect of the cell therapy. Results Ovary size, number of follicle at all developmental stages, and fertility were significantly reduced in the POF group compared with the control. Under hUC-MSC treatment, the ovarian morphology and follicle count were significantly restored, and fertility was significantly increased. By comparing the single and multiple hUC-MSC injection groups, we found that the anti-Müllerian hormone and Ki-67 levels were significantly increased in the multiple hUC-MSC group on D60 after chemotherapy. The expression of stimulating hormone receptors, inhibin α, and inhibin β was significantly restored, and the therapeutic effect was superior to that of the single hUC-MSC injection group. Conclusion These results indicate that hUC-MSCs can restore the structure of injured ovarian tissue and its function in chemotherapy-induced POF mice and ameliorate fertility. Multiple hUC-MSC transplantations have a better effect on the recovery of ovarian function than single hUC-MSC transplantation in POF.
