Genetic and functional analyses of 120 mouse strains have identified a heart regeneration candidate gene that modulates the contractile sarcomeric apparatus. This gene, Tnni3k, controls the frequency of the mononuclear, diploid cardiomyocyte population, which affects cardiomyocyte proliferative potential after injury.
