Fig. 8. Effect of blocking LFA-1 and {alpha}4-integrin on chemotaxis to fMLP. (A) Patterns of cell migration during chemotaxis to fMLP. (B) Chemotactic index (C.I.) of cells migrating to fMLP. (C) Speed of migration to fMLP. Results are shown as mean±s.e.m., n=3. *P<0.05 compared to isotype. §P<0.05 compared with anti-{alpha}4-integrin. {delta}P<0.05 compared with migration on serum protein away from fMLP.
