Abstract (original English)
The human endometrium is a tissue with remarkable plasticity and regenerative capacity. Additionally, endometrial cells can be retrieved using minimally invasive procedures, which makes them an ideal source for reprogramming into a pluripotent state. Endometrial cells were obtained from donors in their fifth decade and reprogrammed into induced pluripotent stem (iPS) cells using retroviral transduction with SOX2, OCT4, KLF4, and MYC. The human endometrial cells displayed accelerated expression of endogenous NANOG and OCT4 during reprogramming compared with neonatal skin fibroblasts. As a result, iPS cell colonies that could be subcultured and propagated were established as early as 12 d after transduction rather than the usually reported 3-4 wk for other cell types. After 3 wk of reprogramming, the human endometrial cells also yielded significantly higher numbers of iPS colonies in comparison with the neonatal skin fibroblasts. Although the efficiency of iPS colony formation varied depending on the donor, the basal level of endogenous expression of the defined factors was positively correlated with reprogramming efficiency. The reprogramming resulted in an average colony-forming efficiency of 0.49 ± 0.10%, with a range from 0.31-0.66%, compared with the neonatal skin fibroblasts, resulting in an average efficiency of 0.03 ± 0.00% per transduction, with a range from 0.02-0.03%.
