Cardiomyogenesis in the Developing Heart Is Regulated by C-Kit–Positive Cardiac Stem Cells

Abstract

Myocyte formation derived from CSC differentiation is the major determinant of cardiac growth during development. Division of c-kit-positive CSCs in the mouse is promoted by spontaneous Ca(2+) spikes, which dictate the pattern of stem cell replication and the generation of a myocyte progeny at all phases of prenatal life and up to one day after birth.
