In vitro and in vivo roles of glucocorticoid and vitamin D receptors in the control of cardiomyocyte proliferative potential

The paper investigates the roles of glucocorticoid and vitamin D receptors in cardiomyocyte proliferation, finding that while they inhibit proliferation in vitro, they are not essential for cell-cycle exit in vivo.

Sympathetic Nerve Activity Promotes Cardiomyocyte Cell-Cycle Arrest And Binucleation

This study shows that sympathetic nerve activity reduces cardiomyocyte proliferation and causes binucleation, which may limit heart regeneration in adults.
