Effect of CXCR7 silencing on tube formation induced by SGC-7901 cells. HUVECs were cocultured with SGC-7901 cells, as described in the “Methods” section. a Representative images of tube-like structures are given for control, NC, and CXCR7shRNA transfected SGC-7901 cells with or without SDF-1. b Quantitative analysis of the number of tubes. Each bar represents mean ± SD from three independent experiments. ***P < 0.001 (as compared with control cells)
