Fig. 4From: SDF-1/CXCR7 axis regulates the proliferation, invasion, adhesion, and angiogenesis of gastric cancer cellsSilencing of CXCR7 inhibits SDF-1-induced enhancement on SGC-7901 cell proliferation in vitro. Cell proliferation was measured by CCK-8 at different time points (0, 24, 48, 72, and 96 h). Each bar represents mean ± SD from three independent experiments. **P < 0.01 (as compared with untransfected cells)Back to article page
