Somatic reprogramming efficiency by expression of defined transcription factors can be enhanced by deletion of p53. He and colleagues found that the microRNA miR-34, which is induced by p53 during reprogramming, inhibits reprogramming, partly by direct repression of pluripotency factors. Deletion of Mir34 from mice increases reprogramming efficiency and kinetics without affecting self-renewal and differentiation.
