MDM4 enables efficient human iPS cell generation from PBMCs using synthetic RNAs.

If iPS cells can be established easily and efficiently using freshly collected blood cells, it will enhance regenerative and personalized medicine. While reports of iPS derivation from blood-derived endothelial progenitor cells using RNA have been documented, none have been reported from peripheral blood-derived mononuclear cells (PBMCs). In this study, we established a method to generate iPS cells from PBMCs using synthetic RNAs and found that MDM4, which suppresses p53, improved reprogramming efficiency.
