Figure 2: (A) The capillary density in myocardium of sham-tumor rats and AMI-tumor rats showed a significant increase compared with AMI rats. The results are expressed as mean ± SEM, n=5. *P< 0.01 and **P< 0.01, vs. sham group;▲▲ P< 0.01 vs . AMI group. (B) The variance analysis of factorial experimental design showed an independent effect of tumor-bearing from AMI on promoting capillary density (F=0.510, P=0.485).
