The aim of this study was to objective to investigate the effects of umbilical cord mesenchymal stem cells on the expression of CYR61, FSH and AMH in mice with premature ovarian failure. For this purpose, thirty SPF female SD mice were selected as the research object, 10 of which were control group, namely group α, and 20 mice with premature ovarian failure model were established by cyclophosphamide. The mice were divided into model group, namely β group and the umbilical cord mesenchymal stem cell transplantation group (γ group), with 10 mice in each group. ELSA method was used to determine the levels of follicle-stimulating hormone (FSH), Luteinizing hormone (LH), estradiol (Estradiol) in serum. The changes of E2, Antimullerian hormone (AMH) and cysteine-rich protein 61 in ovarian tissues were determined by the protein imprinting method. Connective tissue growth factor (CTGF) and caspase-3 protein expression. Results showed that in fertility rate, γ group > α group > β group, the difference was statistically significant (P<0.05), in litter size, α group > γ group > β group, the difference was statistically significant (P<0.05). The levels of serum E2 and AMH in α group > γ group > β group, and the levels of serum FSH and LH in β group > γ group > α group were statistically significant (P<0.05). The growth follicles were α group > γ group > β group, and the atresia follicles were β group > γ group > α group, and there was a statistical difference among all groups (P<0.05). There was no difference in luteal number among the three groups (P>0.05). In terms of CYR61 and CTGF protein expression, α group > γ group > β group, and in terms of caspase-3, β group > γ group > α group had statistical significance (P<0.05). It is concluded that intervention with umbilical cord mesenchymal stem cells can significantly improve the expression levels of CYR61 and AMH, reduce the level of FSH, promote cell survival, improve the reproductive quality of mice, and restore the physiological function of the ovary. It is feasible to treat premature ovarian failure with umbilical cord mesenchymal stem cells.

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.

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.

Mesenchymal stem cells, which are poorly immunogenic and have potent immunosuppressive activities, have emerged as promising cellular therapeutics for the treatment of several diseases. Mesenchymal-like cells derived from Wharton’s Jelly, called umbilical cord matrix stem cells (UCMSCs), reportedly secrete a variety of cytokines and growth factors, acting as trophic suppliers. Here, we used UCMSCs to treat premature ovarian failure (POF). Ovarian function was evaluated by ovulation and the number of follicles. Apoptosis of the granulosa cells (GC) was analyzed by TUNEL staining. We found that after transplantation of the UCMSCs, apoptosis of cumulus cells in the ovarian damage model was reduced and the function of the ovary had been recovered. The sex hormone level was significantly elevated in mice treated with UCMSCs. The number of follicles in the treated group was higher than in the control group. Our results demonstrate that UCMSCs can effectively restore ovary functionality and reduce apoptosis of granulosa cells. We compared the RNA expression of the UCMSCs treated group with the POF model and wild-type control group and found that the UCMSC group is most similar to the wild-type group. Our experiments provide new information regarding the treatment of ovarian function failure.

The end result of a variety of cardiovascular diseases is heart failure. Heart failure patients’ morbidity and mortality rates are increasing year after year. Extracellular vesicles (EVs) derived from human umbilical cord mesenchymal stem cells (HucMSC-EVs) have recently been discovered to be an alternative treatment for heart failure, according to recent research. In this study, we aimed to explore the underlying mechanisms in which HucMSC-EVs inhibited doxorubicin (DOX)-induced heart failure in AC16 cells. An miR-100-5p inhibitor and an miR-100-5p mimic were used to transfect HucMSCs using Lipofectamine 2000. HucMSC-EVs were isolated and purified using the ultracentrifugation method. AC16 cells were treated with DOX combined with HucMSC-EVs or an EV miR-100-5-p inhibitor or EV miR-100-5-p mimic. ROS levels were measured by a flow cytometer. The levels of LDH, SOD, and MDA were measured by biochemical methods. Apoptotic cells were assessed by a flow cytometer. Cleaved-caspase-3 and NOX4 protein expression were determined by Western blot. The experiment results showed that HucMSC-EVs inhibited DOX-induced increased levels of ROS, LDH, and MDA, and decreased levels of SOD which were reversed by an EV miR-100-5-p inhibitor, while EV miR-100-5-p mimic had a similar effect to HucMSC-EVs. At the same time, HucMSC-EV-inhibited DOX induced the increases of apoptotic cells as well as NOX4 and cleaved-caspase-3 protein expression, which were reversed by an EV miR-100-5-p inhibitor. Furthermore, the NOX4 expression was negatively regulated by miR-100-5p. Overexpression of NOX4 abolished the effects in which HucMSC-EVs inhibited DOX-induced ROS, oxidative stress, and apoptosis increases. In conclusion, these results indicate that HucMSC-EVs inhibit DOX-induced heart failure through the miR-100-5p/NOX4 pathway.

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.
