Fig. 3From: Differential action of pro-angiogenic and anti-angiogenic components of Danhong injection in ischemic vascular disease or tumor modelsPAC and AAC displayed bi-directional effects on endothelial cell angiogenesis in tube formation assay. A Representative microscopy image of tube formation in EA.hy926 cells. B Quantitation of in vitro tube formation activity. After incubating for 12 h, numbers of the cellular network were counted in multiple (n = 3) views. The average percentage was calculated. VEGF and PAC promoted tube formation, whereas AAC inhibited tube formation in EA.hy926 cells. Data are presented as mean ± SD. n = 3. *P < 0.05, compared with the control groupBack to article page
