The paper "Mammalian heart renewal by pre-existing cardiomyocytes" published in the journal Nature by Senyo and colleagues (online publication on December 5, 2012), on the other hand, suggests that the endogenous regenerative potential of the adult heart is very limited. The researchers studied the regeneration of cardiomyocytes in mice using... Read more
