A 59-year old healthy man of Han Chinese genetic background donated his peripheral blood mononuclear cells (PBMC). The non-integrating episomal vector system was used to reprogram his PBMCs with the human OSKM (Oct4, Sox2, Kl4 and c-Myc) transcription factors. The pluripotency of transgene-free iPSCs was confirmed by immunocytochemistry for pluripotency markers and by the ability of the iPSCs to differentiate spontaneously into 3 germ layers in vitro. In addition, the iPSC line displayed a normal karyotype. In the studies of disease mechanism, the iPSC line can be used as a control.
