Effect of catechu extracts on the tube and network formation of HMEC-1 and HUVEC cells. (A) Representative photos of the tube formation assay at 24 h. HMEC-1 and HUVEC cells were treated with 0.8 ng/mL and 1.0 ng/mL crude catechu extracts, respectively. The network formation was quantified by the mesh number formation for (B) HMEC-1 and (C) HUVEC cells. Data are presented as means ± SD in three independent experiments. The p-value was calculated versus the control using one-tailed test analysis; p < 0.005 is denoted as **.
