Epigenetic reprogramming during tissue regeneration

Epigenetic control of gene regulation is fundamental to the maintenance of cellular identities during all stages of metazoan life. Tissue regeneration involves cellular reprogramming processes, like dedifferentiation, re-differentiation, and trans-differentiation. Hence, in these processes epigenetic maintenance of gene expression programs requires a resetting through mechanisms that we are only beginning to understand. Here we summarize the current status of these studies, in particular regarding the role of epigenetic mechanisms of cellular reprogramming during tissue regeneration.
