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.展开更多
