From: Tyrosine-kinase inhibition results in EGFR clustering at focal adhesions and consequent exocytosis in uPAR down-regulated cells of Head and Neck cancers

Figure 3

The effect of Tyrosine kinase inhibition on cell adhesion and chemotactic migration: The effect of gefitinib on cell adhesion (A) and chemotactic migration (B) was evaluated on collagen I as ECM. Gefitinib reduced both cell adhesion and chemotactic cell migration in the three cell lines. The inhibitory effect of gefitinib on chemotactic cell migration was more significant in ACCS-AS cells, compared to parental ACCS cells, suggesting a synergism between the dual inhibition of uPAR and EGFR signaling on cellular migration. The low adhesion and chemotactic migration of NA-SCC cells are also shown. The bars represent SD of results of separate wells. *p < 0.05, non-treated versus gefitinib-treated cells.
