Abstract:
Transgene-free human HS5-SV.hiPS line was generated from human cesarean scar-derived fibroblasts using temperature-sensitive Sendai virus vectors carrying Oct4, Sox2, cMyc and Klf4 exogenous transcriptional factors. The viral constructs were eliminated from HS5-SV.hiPS line through heat treatment. Transgene-free HS5-SV.hiPS cells expressed pluripotent associated transcription factors Oct4, Nanog, Sox2, Rex1 and surface markers SSEA-4, TRA-1-60 and OCT4. HS5-SV.hiPS cells formed embryoid bodies and differentiated into three embryonic germ layers in vivo. HS5-SV.hiPS cells maintained their normal karyotype (46, XX) after culture for extended period. HS5-SV.hiPS displayed the similar pattern of DNA fingerprinting to the parenteral scar-derived fibroblasts.
