Abstract

The study is to investigate BMSCs ability to differentiate cardiomyocytes, especially discussed cell generations and 5-Aaz concentration influence on BMSCs capability of proliferation and differentiation into cardiomyocytes during constructing the engineered myocardium-like tissue in vitro. The results have demonstrated that the different concentration of 5-Aza has the influence on proliferation rate of different generations of BMSCs, the second generation BMSCs was superior to the sixth, and tenth generation in proliferation capacity after being induced, and 5-Aza had some influence on proliferation capacity. Rat BMSCs could be differentiated into cardiomyocytes-like cells, which have a good biocompatibility with acellular bovine pericardium, and myocardium-like tissue could be engineered with BMSCs and acellular bovine pericardium in vitro. In conclusion, BMSCs could be induced and differentiated into cardiomyocytes-like cells in vitro. Different generations and different 5-Aza density have influence on the rate of increase of BMSCs, and the engineered myocardium-like tissue could be constructed with BMSCs and acellular bovine pericardium in vitro.
