Fig. 6From: Human placenta-derived mesenchymal stem cells stimulate ovarian function via miR-145 and bone morphogenetic protein signaling in aged ratsSchematic diagram of the modulation of miR-145 expression and BMP-SMAD signaling by hPD-MSC therapies on folliculogenesis. When old female rats were treated with hPD-MSCs, there was a marked reduction in circulating miR-145 levels and restoration of BMP-SMAD1/5 signaling, but not of TGF-β signaling, resulting in the activation of the primordial-to-primary follicle transition. As a result, aged ovaries had increased ovarian reserve and ovarian functionBack to article page
