ABSTRACT Induced pluripotent stem cells (iPSCs) have become important cell sources for genetic disease models, and they have the potential to be cell sources for future clinical therapies. However, invasive tissue sampling reduces the number of candidates who consent to donate cells for iPSC generation. In addition, integrated transgenes can potentially insert at inappropriate points in the genome, and in turn have a direct oncogenic effect. Technical modifications using a combination of activated T cells and a temperature-sensitive mutant of Sendai virus (SeV) can avoid invasive tissue sampling and residual transgene issues in generating iPSCs. Such advances may increase the number of consenting patients for cell donations. Here we present a detailed protocol for the generation of iPSCs from a small amount of human peripheral blood using a combination of activated T cells and mutant SeV encoding human OCT3/4, SOX2, KLF4 and c-MYC; T cell-derived iPSCs can be generated within 1 month of blood sampling.
