Abstract

Embryonic stem (ES) cells are pluripotent cells that can self-renew indefinitely or be induced to differentiate into multiple cell lineages, and thus have the potential to be used in regenerative medicine. Pluripotency transcription factors (TFs), such as Oct4, Sox2, and Nanog, function in a regulatory circuit that silences the expression of key TFs required for differentiation and activates the expression of genes important for maintenance of pluripotency. In addition, proteins that remodel chromatin structure also play important roles in determining the ES cell-specific gene expression pattern. Here we review recent studies demonstrating the roles of enzymes that carry out one facet of chromatin regulation, nucleosome remodeling, in control of ES cell self-renewal and differentiation.
