Abstract

In many works it was shown that Ьone marrow stromal cells (BMSC) transplantation improves heart function. However remains unclear whether the predifferentiation could influence on the damaged myocardial function repare, especially in the increased load settings on the left ventricle (LV). In our study one of three types of autologous BMSC has been transplanted in 1 week after cryodestruction of rat myocardium in peri-infarct areas of LV: undifferentiated, cardiomyocyte-like and endothelial-like predifferentiated BMSC.In 3 weeks after transplantation LV function has been studied using method of dosed pre- and afterloads on the isolated hearts (as provided Ьy Neely preparation). It has been shown, that after all 3 types BMSC transplantation heart showed the best stability to load tests in comparison with control group. However we consider that increase of adaptive reserves of LV myocardium after transplantation all different types of BMSC was realized by various pathways in each group.
