Generation of a pig induced pluripotent stem cell (piPSC) line from embryonic fibroblasts by incorporating LIN28 to the four transcriptional factor-mediated reprogramming: VSMUi001-D.

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.
