In order to ascertain the effects of epidermal growth factor (EGF) on human cancer invasion abilities, three cell lines of human oral squamous cell carcinoma were studied using a phagokinetic track assay and zymography. EGF (1-100 ng/ml) was found to inhibit the growth but enhance the random motility of all three cell lines in a concentration-dependent fashion. Exposure to EGF, dose-dependently, led to an increased production of urokinase-type plasminogen activator and M(r) 92 kD matrix metalloproteinase by the same cells. These results strongly suggest that EGF may promote human squamous cell carcinoma invasion and metastasis.
