Establishment and adipocyte differentiation of polycystic ovary syndrome-derived induced pluripotent stem cells.
OBJECTIVE
To establish a new biological cell model and approach to mimic abnormal lipid metabolism of polycystic ovary syndrome (PCOS) in vitro.


METHODS
Epithelial cells from PCOS patients were reprogrammed to pluripotency by retroviral transduction using defined factors. Morphology, growth characteristics, karyotype, gene expression and differentiation in vitro and in vivo were detected by identification protocol of human embryonic stem cells (ESCs). PCOS-induced pluripotent stem cells (iPSCs) were then induced to differentiate into adipocytes. Ability of the adipocytes for glucose consumption was compared with those from non-PCOS-iPSCs.


RESULTS
iPSCs were successfully generated from PCOS patients' adult cells. Formed iPSC clones had the same characteristics of human ESCs. PCOS-iPSCs were induced to differentiation into normal karyotype adipocytes. Compared to non-PCOS-iPSCs, PCOS-iPSCs had more glucose consumption ability during adipocyte differentiation and development in vitro.


CONCLUSIONS
This protocol provides a new biological cell model and approach for studying pathogenesis of PCOS and discovering potential drugs to treat it.
