Abstract (original English)

Lipid accumulation disrupts mitochondrial dynamics, leading to dysfunctional energy metabolism and increased oxidative stress. However, the relationship between mitochondrial dynamics and ovarian function in therapeutic contexts is still not fully elucidated. Therefore, the objective of this study was to demonstrate whether increased carnitine palmitoyltransferase 1A (CPT1A) expression induced by placenta-derived mesenchymal stem cells (PD-MSCs) improves ovarian function in ovaries of a lipid toxicity-induced rat model by regulating lipid metabolism and mitochondrial dynamics. A rat model of injury was induced through intraperitoneal administration of thioacetamide (TAA) for 12 weeks. During the 8th week of induction, PD-MSCs (2 × 10 6 cells) were transplanted via the tail vein. Initially, we examined the engraftment of PD-MSCs. The inflammatory response (e.g., IL-6, TNFα) and apoptosis (e.g., LDH levels, TUNEL assay) were significantly increased in the non-transplanted (NTx) group compared to the normal group; however, they were significantly decreased in the transplanted (Tx) group compared to the NTx group (* p p p p < 0.05). The levels of sex hormone and follicular development were protected in the Tx group compared to the NTx group. Furthermore, cocultivation of PD-MSCs with etomoxir (CPT1A inhibitor)-treated primary theca cells increased the expression of steroidogenesis.
