Angiopoietin-1 targeted RNA interference suppresses angiogenesis and tumor growth of esophageal cancer

Figure 2 Effect of Ang-1si on HUVEC cell proliferation and chemotaxis. A: HUVEC cell migration was quantified after 6 h, few HUVEC cells migrated as the chemotactic stimulus from Eca109/Ang-1si cells supernatants compared with Eca109 and Eca109/si cells supernatants. ^bP < 0.01; B: HUVEC cells were incubated with the indicated supernatant for 48 h, no difference of proliferative activity of Eca109/Ang-1si cells from Eca109 and Eca109/si cells. ^bP < 0.01.
