Abstract
Neonatal mice display a remarkable ability to regenerate their heart following an injury during the first week of life. A key facet of successful cardiac regeneration is the proliferation of cardiomyocytes to replace the lost cells. Stimulating cardiomyocyte proliferation in the adult heart is a very promising approach to restore cardiac structure and function following injury. Here, we outline our approach to assess cardiomyocyte proliferation following a myocardial injury via the cell cycle markers phospho-histone H3 and Aurora B. We additionally discuss how we assess successful regeneration using wheat germ agglutinin to measure cardiomyocyte size, nuclear staining to quantify cardiomyocyte nucleation, and Trichrome staining to identify myocardial regeneration and scarring in the myocardium.
