Abstract
Polycystic ovary syndrome (PCOS) is a common cause of infertility in women, characterized by metabolic and hormonal irregularities. We investigated the effects of placenta-derived mesenchymal stem cells (PDMSCs) and platelet-rich plasma (PRP), as well as their combination on follicular development, hormonal profile, inflammatory parameters, and insulin resistance in a model of PCOS. In this study, 25 female Wistar rats were randomly allocated into five groups: Sham (given a dose of 1 mL of a 0.5% carboxymethylcellulose (CMC) solution), PCOS (administered 1mg/kg of letrozole (LTZ) dissolved in CMC for 21 days), PDMSC (treated with a single intraovarian dose of PDMSCs), PRP (treated with a single intraovarian dose of PRP), and a combined PDMSC and PRP-treated group. After two weeks, serum and ovarian samples were collected for biochemical and histological analyses. Our results demonstrated that the simultaneous administration of PDMSCs and PRP had a synergistic effect compared to monotherapy, leading to an increase in estradiol (E2) and follicle-stimulating hormone (FSH) serum levels, a decrease in luteinizing hormone (LH) and testosterone levels, as well as inflammatory factors. Moreover, the combined therapy was associated with significantly lower levels of the homeostatic model of insulin resistance (HOMA-IR), fasting insulin (FINS), and blood glucose (FBG) compared to monotherapy. The combined treatment also caused a significant reduction in cystic follicles and an elevated number of corpus luteum, primordial, primary, secondary, and antral follicles. In conclusion, the combination of PRP and PDMSCs may have an ameliorative effect on modifying metabolic abnormalities and accelerating ovarian regeneration in PCOS.
