Young at heart: a novel window to cardiac regeneration
A new study in neonatal mice carried out by the Center for Regenerative Medicine in Barcelona (CMR[B]), in collaboration with the Institute of Bioengineering of Catalonia (IBEC) and the University of Barcelona (UB), has established that the ability of the heart to regenerate after a wound is related to the stiffness of the cellular environment, rather than to the proliferative capacity of the cardiac cells, narrowing the window of regeneration to 48 hours after birth.
