Pig induced pluripotent stem cell (piPSC) line was generated from embryonic fibroblast cells using retroviral transduction approaches carrying human transcriptional factors: OCT4, SOX2, KLF4, c-MYC and LIN28. The generated piPSC line, VSMUi001-D, was positive for alkaline phosphatase activity and expressed the pluripotency associated transcription factors including OCT4, SOX2, NANOG and surface markers SSEA-1, all iPSC hallmarks of authenticity. Furthermore, VSMUi001-D exhibited a normal karyotype and formed embryoid bodies in vitro and teratomas in vivo. Upon cardiac differentiation, VSMUi001-D displayed spontaneous beating and expressed cardiomyocyte markers, like cardiac Troponin T.
猪诱导多能干细胞（piPSC）系是利用携带人类转录因子OCT4、SOX2、KLF4、c-MYC和LIN28的逆转录病毒转导方法，从胚胎成纤维细胞中产生的。所产生的piPSC系VSMUi001-D碱性磷酸酶活性呈阳性，并表达多能性相关转录因子，包括OCT4、SOX2、NANOG以及表面标志物SSEA-1，这些都是诱导多能干细胞真实性的所有标志性特征。此外，VSMUi001-D表现出正常的核型，在体外形成胚状体，在体内形成畸胎瘤。在心脏分化时，VSMUi001-D表现出自发搏动并表达心肌细胞标志物，如心肌肌钙蛋白T。
