Here, combined multiparametric surface marker analysis with single cell transcriptional profiling and in vivo transplantation, identify the main fetal cardiac populations and their progenitors. We found that cardiomyocytes at different stages of differentiation co-exist during development. We identified a population of immature HSA\/CD24\n                  <jats:sup>+<\/jats:sup>\n                  cardiomyocytes that persists throughout life and that, unlike other cardiomyocyte subsets, actively proliferates up to one week of age and engraft cardiac tissue upon transplantation.

Our work identified cell surface signatures that allow the prospective isolation of cardiomyocytes at any developmental stage and the detection of adult cardiomyocytes poised for activation in response to ischemic stimuli.
