摘要
A recent study from Naqvi et al1 in Cell shows that in mice during preadolescence, cardiomyocytes undergo a burst of proliferation that is related to a thyroid hormone surge. This study challenges the conventional model of the timing of terminal differentiation and provides a direction for further mechanistic research on cardiomyocyte proliferation and differentiation. © 2014 American Heart Association, Inc.
