Abstract: Disclosed are findings that: (a) induced pluripotent stem cells derived from aged donors (A-iPSC) show increased genomic instability, a defect in apoptosis, a defect in glucose metabolism, and a blunted DNA damage response are compared to those derived from young donors (Y-iPSC); and (b) inhibition of excessive glutathione-mediated H202 scavenging activity, found to be associated with A-iPSC and in turn inhibiting DNA damage response and apoptosis, substantially rescues these defects and reduces the oncogenic potential of A-iPSC. Supplementation of pluripotency factor ZSCAN 10 (shown to be poorly activated in A-iPSC and to act upstream of glutathione involvement), e.g.

Abstract: The present technology relates generally to the generation of induced pluripotent stem cells (iPSCs). In particular aspects, the present technology relates generally to methods for generating iPSCs from non-pluripotent cells, such as aged somatic cells, wherein the iPSCs are characterized by improved genomic stability, improved DNA damage response, increased ZSCAN10 expression, reduced GSS expression, and/or increased reprogramming efficiency.
