HGF and cancer: Consistently, these factors were correlated with cancer-associated biological process, such as cell proliferation (HGF: Hepatocyte growth factor and FGF2: Fibroblast growth factor 2), cell migration (CCL20: Chemokine (C-C motif ligand 20, CXCL5: C-X-C motif chemokine 5, IL-6: Interleukin 6) and cell communication (ICAM-1: Intercellular adhesion molecule 1) (Figure.
