The cell-autonomous and non –cell-autonomous roles of the Hippo pathway in heart regeneration

Cardiomyocytes are differentiated heart muscle cells with minimal self-renewal ability. Thus, loss of cardiomyocytes from cardiovascular disease and injury cannot be effectively replenished. Recent studies in animal models have indicated that induction of endogenous cardiomyocyte proliferation is essential for cardiac renewal and that inhibiting the Hippo signaling pathway can stimulate cardiomyocyte proliferation and heart regeneration. Increasing evidence has suggested that cardiomyocyte proliferation requires a permissive microenvironment that consists of multiple cell types.
