Abstract
Cell‐type‐ and cell‐state‐specific patterns of covalent modifications on DNA and histone tails form global epigenetic profiles that enable spatiotemporal regulation of gene expression. These epigenetic profiles arise from coordinated activities of transcription factors and epigenetic modifiers, which result in cell‐type‐specific outputs in response to dynamic environmental conditions and signalling pathways. Recent mouse genetic and functional studies have highlighted the physiological significance of global DNA and histone epigenetic modifications in skin. Importantly, specific epigenetic profiles are emerging for adult skin stem cells that are associated with their cell fate plasticity and proper activity in tissue regeneration. We can now begin to draw a more comprehensive picture of how epigenetic modifiers orchestrate their cell‐intrinsic role with microenvironmental cues for proper skin development, homeostasis and wound repair. The field is ripe to begin to implement these findings from the laboratory into skin therapies.
