Generation of transgene-free human induced pluripotent stem cells from erythroblasts in feeder-free conditions

This protocol describes the generation and characterization of human induced pluripotent stem cells (hiPSCs) from erythroblasts. A key difference with classical protocols is the reprogramming of erythroblasts from a simple blood draw as opposed to fibroblasts/keratinocytes, which requires a biopsy. Moreover, working with erythroblasts ensures that no recombination of the TCR/BCR genes occurs, as opposed to T cells and whole peripheral blood mononuclear cells-based approaches. Last, this approach uses non-integrative episomes ensuring no integration of transgenes into the hiPSCs genome. For complete details on the use and execution of this protocol, please refer to Perriot et al. (2018).
