Abstract

For many years, stem cell metabolism was viewed as a byproduct of cell fate status rather than an active regulatory mechanism; however, there is now a growing appreciation that metabolic pathways influence epigenetic changes associated with lineage commitment, specification, and self-renewal. Here we review how metabolites generated during glycolytic and oxidative processes are utilized in enzymatic reactions leading to epigenetic modifications and transcriptional regulation. We discuss how "metabolic reprogramming" contributes to global epigenetic changes in the context of naive and primed pluripotent states, somatic reprogramming, and hematopoietic and skeletal muscle tissue stem cells, and we discuss the implications for regenerative medicine.
