人羊水干细胞来源的外泌体(HuAFSC-exosome)移植被认为是治疗卵巢早衰(POF)的一种有前途的方法。然而,其机制仍不清楚。在这项研究中,从CD 44 +/CD 105+的HuAFSC亚群中分离和富集外泌体,并将外泌体移植到体外和体内POF模型中。我们的结果证实了由CD 44 +/CD 105 + HuAFSC产生的外泌体可以在小鼠POF模型中实现治疗效果。我们的研究还表明,携带miR-369- 3 p的CD 44 +/CD 105 + HuAFSC-exosomes能够特异性下调YAF 2的表达,抑制PDCD 5/p53的稳定性,减少卵巢颗粒细胞(OGC)的凋亡,从而对POF发挥治疗作用。这些机制的知识表明,由CD 44 +/CD 105 + HuAFSC-外泌体携带的miRNA对于POF的治疗至关重要。这将有助于干细胞的临床应用。
Human amniotic fluid stem cell-derived exosome (HuAFSC-exosome) transplantation is considered a promising treatment for premature ovarian failure (POF). However, its mechanism remains unclear. In this study, exosomes were isolated and enriched from HuAFSC subsets of CD44+/CD105+, and the exosomes were transplanted into a POF model in vitro and in vivo. Our results confirmed that the exosomes produced by CD44+/CD105+ HuAFSCs could achieve therapeutic effects in a mouse POF model. Our research also showed that CD44+/CD105+ HuAFSC-exosomes carrying miR-369-3p could specifically downregulate the expression of YAF2, inhibit the stability of PDCD5/p53, and reduce the apoptosis of ovarian granulosa cells (OGCs), thereby exerting therapeutic effects on POF. Knowledge of these mechanisms demonstrates that miRNAs carried by CD44+/CD105+ HuAFSC-exosomes are critical to the therapy of POF. This will be useful for the clinical application of stem cells.
