Another of our studies demonstrated that chemokine (C-X-C motif) ligand 1 (CXCL1), which is produced from diffuse-type gastric cancer (DGC) cells, is closely associated with the recruitment of BM-MCs into tumor stroma via chemokine (C-X-C motif) receptor 2 (CXCR2) of BM-MCs [8]. Here, CXCL1 is linked to neoplasm.
