Episomal plasmid-based generation of an iPSC line from an 83-year-old individual carrying the APOE4/4 genotype: i10984.


PMID 27789402

Abstract

In this study, lymphoblastoid cells derived from a 83-year old individual with a 15year history of progressive presenile dementia, were used to generate iPS cells, employing episomal plasmids expressing OCT4, SOX2, LIN28, L-MYC and a p53 shRNA. The individual was homozygous for the APOE4 allele. The resulting iPS cells had a normal karyotype, retained the APOE4/4 genotype, expressed pluripotency markers, were free of genomically integrated plasmids, and could be differentiated into cell type representatives from the three germ layers in vitro.
