Reprogramming of mouse and human somatic cells can be achieved by ectopic expression
of transcription factors, but with low efficiencies. We report that DNA methyltransferase and
histone deacetylase (HDAC) inhibitors improve reprogramming efficiency. In particular,
valproic acid (VPA), an HDAC inhibitor, improves reprogramming efficiency by more than
100-fold, using Oct4-GFP as a reporter. VPA also enables efficient induction of pluripotent
stem cells without introduction of the oncogene c-Myc.
Abstract

VPA also enables efficient induction of pluripotent stem cells without introduction of the oncogene c-Myc.
