abstract = {Injury to muscle brings about the activation of stem cells,
which then generate new myocytes to replace damaged tissue.
We demonstrate that this activation is accompanied by a
dramatic change in the stem-cell methylation pattern that
prepares them epigenetically for terminal myocyte
differentiation. These de- and de novo methylation events
occur at regulatory elements associated with genes involved
in myogenesis and are necessary for activation and
regeneration. Local injury of one muscle elicits an almost
identical epigenetic change in satellite cells from other
muscles in the body, in a process mediated by circulating
factors. Furthermore, this same methylation state is also
generated in muscle stem cells (MuSCs) of female animals
following pregnancy, even in the absence of any injury.
Unlike the activation-induced expression changes, which are
transient, the induced methylation profile is stably
maintained in resident MuSCs and thus represents a molecular
memory of previous physiological events that is probably
programmed to provide a mechanism for long-term adaptation.},
