Generation of nonviral integration-free human iPS cell line KISCOi001-A from normal human fibroblasts, under defined xeno-free and feeder-free conditions.

ABSTRACT

KISCOi001-A is a healthy feeder-free and fully characterized human induced pluripotent stem (iPS) cell line cultured under xeno-free and defined conditions. The cell line is generated from normal human foreskin fibroblasts with non-integrating episomal plasmid vectors encoding OCT4, SOX2, KLF4, NANOG, LIN28, nontransforming L-MYC and dominant negative p53. The generated iPS cells are transgene-free and their pluripotency is confirmed by the expression of stem cell markers and capacity to differentiate into the cells of ectoderm, endoderm and mesoderm while their identity and karyotype stability is confirmed with Genomic assays.
