A 74-year-old Alzheimer's Disease (AD) woman patient donated her peripheral blood mononuclear cells (PBMC). Non-integrating episomal vector system were used to reprogram their PBMCs with human OKSM (OCT3/4, KLF4, SOX2, and c-MYC) transcription factors. Immunocytochemistry and flow cytometry for pluripotency makers confirmed the pluripotency of transgene-free iPSCs. Pluripotency was confirmed by the ability of iPSCs to spontaneously differentiate three germ layers in vitro as well. The newly generated human iPSC from PBMCs of a 74 year-old Alzheimer's disease woman can be used for studying further disease mechanisms of Alzheimer's Disease (AD).
