The primary human dermal fibroblasts (PHDFs) frombreast cancer patientwere obtained to generate the human induced pluripotent stem cell line GPCCi001-A via lentiviral transfection. Thus, a modified EF1a-hSTEMCCA-loxP with tetO operator which regulates transgene expression was used. This method takes advantage of epigenetic regulation of transcription and allows for stable silencing of the reprogramming factors in obtained hiPS cells. To increase the potential utility of hiPSCs for clinical applications, they were adapted to feeder-and xeno-free conditions. The pluripotency of GPCCi001-A cell line and ability to differentiate into three germ layers was confirmed.
