CXCL5 and gastric cancer: Data from chemotaxis assay indicated that M0, MS and MR macrophages could attract THP-1 cells, the chemotaxis-inducing effect of MR macrophages was significantly stronger than that of M0 and MS macrophages (p < 0.001; p < 0.001), and the CXCL5 neutralizing antibody could weakened the MR macrophages-induced chemotaxis in gastric cancer (Fig. 7A; p < 0.001).
