Generating iPSCs from immunologically immature newborn umbilical cord blood mononu- clear cells (UCBMCs) is of great significance. Here we report generation of human iPSCs with great efficiency from UCBMCs using a dox-inducible lentiviral system carrying four Yamanaka factors. We generated these cells by optimizing the existing iPSC induction protocol. The UCBMC-derived iPSCs (UCB-iPSCs) have characteristics that are identical to pluripotent human embryonic stem cells (hESCs). This study highlights the use of UCBMCs to generate highly functional human iPSCs that could accelerate the development of cell-based regenerative therapy for patients suffering from various diseases.展开更多

However, integrating retroviral (Takahashi et al., 2007) or lentiviral (Hockemeyer et al., 2008) gene delivery systems and the exogenous oncogene c-Myc (Takahashi et al., 2007; Hockemeyer et al., 2008) have been typically used in the reprogramming process, which could increase risks of insertional mutations or epigenetic abnormalities and conse- quently pose biosecurity concerns for basic research and clinical applications of hiPSCs.展开更多
