Activated Human Umbilical Cord Blood Platelet-Rich Plasma Enhances the Beneficial Effects of Human Umbilical Cord Mesenchymal Stem Cells in Chemotherapy-Induced POF Rats

ABSTRACT: Saving the ovarian function of premature ovarian failure (POF) patients undergoing chemotherapy is an important problem in the field of reproductive medicine. At present, human umbilical cord mesenchymal stem cells (HucMSCs) have been used in the treatment of POF, but the effect is still not optimal. The purpose of this study was to determine whether human umbilical cord blood platelet-rich plasma (ucPRP) enhances the beneficial effects of HucMSCs in the treatment of POF. First, we observed the effects of changes in the biological activity of ucPRP on HucMSCs in vitro. Subsequently, we tracked the distribution and function of the HucMSCs in POF rats, and the rats' estrus cycle and serum sex hormones, follicular development, ovarian angiogenesis, ovarian granulosa cell proliferation, and apoptosis were assessed. The results of the study showed that the addition of ucPRP in vitro accelerates proliferation and reduces apoptosis of the HucMSCs while upregulating the stemness gene of the HucMSCs. The combined transplantation of HucMSCs and ucPRP resulted in more stem cells being retained in the ovaries of POF rats, the estrus cycle of the POF rats being restored, the levels of serum E2, AMH, and FSH improving, and damaged follicles beginning to grow. Finally, we confirmed that the potential mechanism of the combination of HucMSCs and ucPRP to rescue the ovarian function of POF rats is to promote ovarian angiogenesis and to promote the proliferation and reduce the apoptosis of ovarian granulosa cells. The upregulation of AMH and FHSR expression and the downregulation of caspase-3 expression in granulosa cells are potential mechanisms for the recovery of ovarian function. Our research results suggest that the combined application of HucMSCs and ucPRP is a safe and efficient transplantation program for the treatment of POF, thus providing a reliable experimental basis for the clinical application of stem cell therapy in POF.

Project description:Study questionCan human umbilical cord platelet-rich plasma (hUC-PRP) efficiently treat endometrial damage and restore fertility in a preclinical murine model?Summary answerLocal application of hUC-PRP promotes tissue regeneration and fertility restoration in a murine model of Asherman syndrome and endometrial atrophy (AS/EA).What is known alreadyAS/EA are well-described endometrial pathologies that cause infertility; however, there are currently no gold-standard treatments available. Recent reports have described the successful use of human platelet-rich plasma in reproductive medicine, and its regenerative potential is further enhanced using hUC-PRP, due to the ample growth factors and reduced pro-inflammatory cytokines in the latter.Study design size durationhUC-PRP (n = 3) was processed, characterized and delivered locally to endometrial damage in a murine model (n = 50). The hUC-PRP was either used alone or loaded into a decellularized porcine endometrium-derived extracellular matrix (EndoECM) hydrogel; endometrial regeneration, fertility outcomes and immunocompatibility were evaluated 2 weeks following treatment administration.Participants/materials setting methodsUmbilical cord blood was obtained from women in childbirth. Endometrial damage (mimicking AS/EA) was induced using ethanol in 8-week-old C57BL/6 mice, and treated with the most concentrated hUC-PRP sample 4 days later. Characterization of hUC-PRP and immunotolerance was carried out with multiplex technology, while uterine samples were analyzed by immunohistochemistry and quantitative PCR. The number of embryos and their morphology was determined visually.Main results and the role of chancePlatelet density was enhanced 3-fold in hUC-PRP compared to that in hUC blood (P < 0.05). hUC-PRP was enriched with growth factors related to tissue regeneration (i.e. hepatocyte growth factor, platelet-derived growth factor-BB and epidermal growth factor), which were released constantly (in vitro) when hUC-PRP was loaded into EndoECM. Both treatments (hUC-PRP alone and hUC-PRP with EndoECM) were immunotolerated and caused significantly regeneration of the damaged endometrium, evidenced by increased endometrial area, neoangiogenesis, cell proliferation and gland density and lower collagen deposition with respect to non-treated uterine horns (P < 0.05). Additionally, we detected augmented gene expression of Akt1, VEGF and Ang, which are involved in regenerative and proliferation pathways. Finally, hUC-PRP treatment restored pregnancy rates in the mouse model.Large scale dataN/A.Limitations reasons for cautionThis proof-of-concept pilot study was based on a murine model of endometrial damage and the use of EndoECM requires further validation prior to clinical implementation for women affected by AS/EA.Wider implications of the findingsThe local administration of hUC-PRP has high impact and is immunotolerated in a murine model of AS/EA, as has been reported in other tissues, making it a promising candidate for heterologous treatment of these endometrial pathologies.Study funding/competing interestsThis study was supported by the Ministerio de Ciencia, Innovación y Universidades; Conselleria de Innovación, Universidades, Ciencia y Sociedad Digital, Generalitat Valenciana; and Instituto de Salud Carlos III.
