Epigenetic regulation of gene expression is fundamental in the maintenance of cellular identity and the regulation of cellular plasticity during tissue repair. In fact, epigenetic modulation is associated with the processes of cellular de-differentiation, proliferation, and re-differentiation that takes place during tissue regeneration. In here we explore the epigenetic events that coordinate tissue repair in lower vertebrates with high regenerative capacity, and in mammalian adult stem cells, which are responsible for the homeostasis maintenance of most of our tissues. Finally we summarize promising CRISPR-based editing technologies developed during the last years, which look as promising tools to not only study but also promote specific events during tissue regeneration.
