Additional file 2: of Tumor-derived exosomes induce N2 polarization of neutrophils to promote gastric cancer cell migration

Figure S2. BGC-CM-treated neutrophils promoted gastric cancer cell proliferation and endothelial cell tube formation. A. ROS production in BGC-CM-treated neutrophils was measured by flow cytometric analysis. B. Wright’s stain for BGC-CM-treated neutrophils. Magnification, 200×. C. The proliferation rate of gastric cancer cells treated with supernatant from BGC-CM-treated neutrophils was measured by CCK8 assay. D. Tube formation assay for endothelial cells following treatment with supernatant from BGC-CM-treated neutrophils. E. Western blot assays for p38 and Akt expression in neutrophils treated with BGC-CM. **P<0.01, and *P
