During heart regeneration, myocardial injury and CM loss induce the dedifferentiation of a fraction of CMs (pink). These CMs reenter the cell cycle, produce new CMs, and replenish the lost CMs. CMs that are generated from cell division re-differentiate to a fully mature state to improve heart contraction.
