Abstract
Background: Mesenchymal stem cells (MSCs) have shown potential in repairing chemotherapy-induced premature ovarian failure (POF). However, challenges such as stem cell loss and immune phagocytosis post-transplantation hinder their application. Due to easy and safe handling, in vitro ovarian culture is widely available for drug screening, pathophysiological research, and in vitro fertilization. MSCs could exhibit therapeutic capacity for ovarian injury, and avoid stem cell loss and immune phagocytosis in vitro tissue culture system. Therefore, this study utilizes an in vitro ovarian culture system to investigate the reparative potential of human umbilical cord mesenchymal stem cells (hUCMSCs) and their mechanism.
Methods: In this study, a chemotherapy-induced POF model was established by introducing cisplatin in vitro ovarian culture system. The reparative effects of hUCMSCs on damaged ovarian tissue were validated through Transwell chambers. Tissue histology examination, immunohistochemical staining, Western blotting, and RT-PCR were employed to evaluate the expression effects of hUCMSCs on ferroptosis and fibrosis-related genes during the process of repairing cisplatin-induced POF.
Results: Cisplatin was found to activate ovarian follicles in vitro POF model. Transcriptomic sequencing analysis revealed that cisplatin could activate genes associated with ferroptosis. hUCMSCs alleviated cisplatin-induced POF by suppressing the expression of ferroptosis. Moreover, inhibiting ferroptosis by hUCMSCs also ameliorated ovarian hormone levels and reduced the expression of fibrosis-related factors α-SMA and COL-I in the ovaries.
Conclusions: This study confirms that cisplatin-induced ovarian damage via ferroptosis in vitro POF model, and hUCMSCs repair ovarian injury by inhibiting the ferroptosis pathway and suppressing fibrosis. This research contributes to evaluating the effectiveness of hUCMSCs in treating chemotherapy-induced POF by inhibiting ferroptosis in an in vitro ovarian culture system and provides a potential therapeutic strategy for chemotherapy-induced POF.
