Adult mammalian hearts cannot repair by themselves after injury due to limited proliferation of cardiomyocytes; removal of cell cycle blocker and/or addition of drugs that boost proliferation of cardiomyocytes provide potential means to cardiac regeneration. Three publications that appeared recently in Nature and Cell Research now provide new hope to the treatment of heart injuries.
