Figure 7  Effects of IFN-β on HUVEC proliferation as evaluated by trypan blue dye exclusion tests. At 1 day after HUVEC seeding, 0 or 10 ng/mL of IFN-β was added. Data with bars represent mean±SD (n=3). No significant difference (P<0.05) between 0 ng/mL of IFN-β (blue line) and 10 ng/mL of IFN-β (red line) was observed at each time point according to Student t test. HUVEC indicates human umbilical vein endothelial cell; IFN, interferon.
