OBJECTIVE: We sought to assess the effect of extracellular matrix and hepatocyte growth factor/scatter factor (HGF/SF) on the growth and motility of cultured squamous cell carcinoma of the head and neck (SCCHN) cells. METHODS: Cultured cells were incubated in the presence of HGF/SF. The effect of HFG/SF on cell growth, motility, and phosphorylation of the signaling proteins FAK and Erk was determined. RESULTS: HGF/SF is both mitogenic and motogenic to the human SCCHN cell line FaDu. Incubation of FaDu cells in the presence of HGF/SF led to a rapid increase in phosphorylation of both FAK and the growth-promoting kinase Erk. HGF/SF-induced phosphorylation of FAK and Erk was observed in both detached and attached SCCHN cells. However, phosphorylation was much greater in attached cells. CONCLUSIONS AND SIGNIFICANCE: The mitogenic and motogenic activities of HGF/SF may contribute to the pathogenesis of SCCHN in vivo.
