Transplantation of engineered tissue patches containing either progenitor cells or
cardiomyocytes for cardiac repair is emerging as an exciting treatment option for patients
with postinfarction left ventricular remodeling. The beneficial effects may evolve directly from
remuscularization or indirectly through paracrine mechanisms that mobilize and activate
endogenous progenitor cells to promote neovascularization and remuscularization, inhibit
apoptosis, and attenuate left ventricular dilatation and disease progression. Despite …
Transplantation of engineered tissue patches containing either progenitor cells or cardiomyocytes for cardiac repair is emerging as an exciting treatment option for patients with postinfarction left ventricular remodeling. The beneficial effects may evolve directly from remuscularization or indirectly through paracrine mechanisms that mobilize and activate endogenous progenitor cells to promote neovascularization and remuscularization, inhibit apoptosis, and attenuate left ventricular dilatation and disease progression. Despite encouraging results, further improvements are necessary to enhance current tissue engineering concepts and techniques and to achieve clinical impact. Herein, we review several strategies for cardiac remuscularization and paracrine support that can induce cardiac repair and attenuate left ventricular dysfunction from both within and outside the myocardium.
