摘要
The reprogramming of differentiated cells into induced pluripotent stem cells (iPSCs) can be achieved by ectopic expression of defined transcription factors (Oct3/4, Sox2, Klf4 and c-Myc). However, to date, some iPSCs have been generated using viral vectors; thus, unexpected insertional mutagenesis in the target cells would be a potential risk. Here we report reprogramming of siPSCs (gene silencing-induced pluripotent stem cells) from mouse neonatal cardiomyocytes (CMs) by combining TGF-β signal inhibition and connexin43 (Cx43) silencing, and show that siPSCs show pluripotency in vitro and in vivo. Our novel non-insertional mutagenesis technique may provide a means for iPSC generation.
