Figure 3. Inhibition of cell proliferation of human umbilical vein endothelial cells by small interfering RNA–targeting tissue factor–2. The cell growth of small interfering RNA–targeting tissue factor (TF-siRNA)-2 and vascular endothelial growth factor (VEGF)-siRNA–transfected human umbilical vein endothelial cells (HUVECs) was significantly attenuated in a time-dependent manner compared with the blank control group. *, p<0.01 versus blank control and nonspecific (NS)-siRNA.
