VWF and myocardial infarction: (vWF+ vessel density per HPF: DMEM group 34±2, BMMNCs group 41±2, BMMNCs+AngII+Valsartan group 56±3, BMMNCs+CGP42112A group 60±2, BMMNCs+AngII+Valsartan+PD123319 group 38±2, P<0.001; alpha-SMA+ vessel density per HPF: DMEM group 20±1, BMMNCs group 25±2, BMMNCs+AngII+Valsartan group 35±3, BMMNCs+CGP42112A group 38±2, BMMNCs+AngII+Valsartan+PD123319 group 23±2, P<0.001).These results implicated that transplantation of AT2R stimulated BMMNCs resulted in enhanced angiogenesis during post-MI remodeling process (Figure 8 A to C).
