Adiponectin preserves follicles through ADIPOR1/ADIPOR2-driven fatty acid metabolism

Area of Science:

• Reproductive biology
• Metabolic endocrinology
• Stem cell therapy

Background:

• Adiponectin regulates metabolism and insulin sensitivity.
• Ovarian lipid accumulation is linked to polycystic ovary syndrome (PCOS).
• Current PCOS therapies have limitations and side effects.

Purpose of the Study:

• To investigate if placenta-derived mesenchymal stem cells (PDMSCs) can mitigate ovarian lipotoxicity.
• To determine if PDMSCs restore adiponectin signaling in ovarian dysfunction.
• To evaluate PDMSCs as a potential therapy for PCOS.

Main Methods:

• A thioacetamide (TAA)-induced rat model of ovarian lipotoxicity was treated with PDMSCs.
• Hepatic and ovarian tissues were analyzed post-transplantation.
• PDMSCs were co-cultured with ovarian cells, with or without adiponectin receptor (ADIPOR1/2) knockdown.

Main Results:

• PDMSC transplantation improved insulin resistance, dyslipidemia, and restored tissue architecture.
• PDMSCs increased adiponectin levels and upregulated ADIPOR1/2 in ovarian tissue.
• Ovarian lipid accumulation decreased, and reproductive hormones normalized, indicating restored metabolic and reproductive function.

Conclusions:

• PDMSCs ameliorate metabolic dysfunction and ovarian lipotoxicity via adiponectin signaling.
• PDMSCs restore both metabolic and reproductive health by reprogramming mitochondrial metabolism.
• PDMSC therapy shows promise for PCOS and metabolic-associated ovarian dysfunction.
