Small molecules will need to be identified and/or developed that target protein classes limiting reprogramming efficiency. A specific class of proteins includes epigenetic regulators that silence, or minimize expression, of pluripotency genes in differentiated cells. To better understand the role of specific epigenetic modulators in reprogramming, we have used shRNA delivered by lentivirus to assess the significance of individual epi-proteins in reprogramming pluripotent gene expression.
