PPARG and polycystic ovary syndrome: Therefore, the present pilot study examined whether PPARγ and CEBPα overexpression combined with enhanced lipid accumulation during adipogenesis in vitro in this subgroup of PCOS ASCs is accompanied by changes in chromatin accessibility and/or transcriptional regulation compared to control stem cells, and if so, whether functional differences also exist in the total content and de novo synthesis of fatty acids in the newly-formed adipocytes derived from those ASCs.
