Inhibition of the p53–p21 axis increases reprogramming efficiency of somatic cells into induced pluripotent stem cells (iPSCs). Here the authors show that depletion of the pro-apoptotic factor PUMA, acting downstream of p53, increases reprogramming efficiency, providing new insights into the roles of p53 in reprogramming.
