Abstract (original English)

The chemotherapeutic drug cyclophosphamide (CTX) may damage the ovarian tissue of females and induce premature ovarian insufficiency (POI). This study aimed to investigate the therapeutic effect of adipose-derived mesenchymal stem cell-conditioned medium (ADSC-CM) on CTX-induced POI mice, and to provide new support for the clinical use of cell-free therapy for POI. Female mice were treated with CTX intraperitoneal injection for 2 weeks, followed by ADSCs or ADSC-CM by intravenous injection for 2 weeks. At the end of the experiment, various parameters were assessed, including ovarian interstitial fibrosis, cell proliferation, follicular count, the levels of follicle-stimulating hormone (FSH) and estradiol (E 2 ), and the expression of gonadal hormone receptor. Additionally, we assessed the levels of oxidative stress, apoptosis, and apoptosis signal-regulating kinase 1 (ASK1)/c-Jun N-terminal kinase (JNK) signaling pathway-related proteins and genes in ovarian tissue. The results showed that ADSCs or ADSC-CM treatment reduced ovarian interstitial fibrosis, promoted the proliferation of cells in the follicles, and increased the number of follicles and ovarian function. In addition, ADSCs and ADSC-CM also reduced the levels of ovarian oxidative stress, decreased the apoptosis of granulosa cells (GCs), and inhibited the activation of ASK1/JNK signaling pathway. In conclusion, our st
