Figure 2. The epicardium as a niche for cardiac progenitor cells.

Figure 2

During development, the epicardium regulates myocardial proliferation via FGF signaling, and recent studies indicate that cardiomyocytes arise from the subepicardium during cardiac regeneration. Given these roles, the epicardium may serve as a niche for developing cardiac progenitor cells.
