dc.description.abstractLittle is known about the cardioprotective effects against heart failure (HF), the effects on differentiation of bone marrow-derived mononuclear cell (BMMNC), and the biocompatibility of BMMNC-seeded biodegradable poly-glycolide-co-caprolactone (PGCL) scaffolds in a myocardial infarction (MI) animal model. This study hypothesized that implantation of a BMMNC-seeded PGCL scaffold into the epicardial surface in a rat MI model would be biocompatible, induce BMMNC migration into infarcted myocardium, and effectively improve left ventricular (LV) systolic dysfunction. One week after the implantation of a BMMNC-seeded PGCL scaffold, BMMMC showed migration into the epicardial region. Four weeks after implantation, augmented neovascularization was observed in infarcted areas and in infarct border zones. Some BMMNCs exhibited the presence of alpha-MHC and troponin I, markers of differentiation into cardiomyocytes. In echocardiographic examinations, BMMNC-seeded PGCL scaffold and non-cell-seeded simple PGCL scaffold groups effectively reduced progressive LV dilatation and preserved LV systolic function as compared to control rat MI groups. Thus, BMMNC-seeded PGCL scaffolding influences BMMNC migration, differentiation to cardiomyocytes, and induction of neovascularization, ultimately effectively lessening LV remodeling and progressive LV systolic dysfunction. PGCL scaffolding can be considered as an effective treatment alternative in MI-induced advanced HF. (c) 2006 Elsevier Ltd. All rights reserved.-
