Extracellular vesicles derived from differentiated granulosa-like cells restore the ovarian function of rats with premature ovarian insufficiency.

ABSTRACT: Specifically differentiated cells exhibit greater therapeutic efficacy than mesenchymal stem cells (MSCs), and extracellular vesicles (EVs) present therapeutic benefits similar to those of parental cells and fewer safety issues. Ovarian granulosa cells (OGCs) play a critical role in the pathogenesis of premature ovarian insufficiency (POI), a common gynecological disease that can cause infertility and has no effective treatment. Here, we investigated whether umbilical cord mesenchymal stem cells (UCMSCs) can differentiate into ovarian granulosa-like cells (GLCs) and whether GLC-EVs are more effective in restoring ovarian function than UCMSC-EVs are in POI model rats. Here, we differentiated rat UCMSCs (rUCMSCs) into GLCs in vitro using cytokines and hormones and isolated GLC-EVs. We then u
