We report a simple method, using p53 suppression and nontransforming L-Myc, to generate
human induced pluripotent stem cells (iPSCs) with episomal plasmid vectors. We generated
human iPSCs from multiple donors, including two putative human leukocyte antigen (HLA)-
homozygous donors who match∼ 20% of the Japanese population at major HLA loci; most
iPSCs are integrated transgene-free. This method may provide iPSCs suitable for
autologous and allologous stem-cell therapy in the future.
