This paper identifies a novel population of progenitor cells that come from the pro-epicardial organ. These cells, which express the transcription factor Tbx18, migrate to the outer surface of the heart to form the epicardium, and they also contribute to myocytes in the ventrical septum and atrial and ventricular walls, as well as to cardiac fibroblasts and coronary smooth muscle cells. Thus these progenitors seem to be pluripotent.
