Fig. 2. Random migration (chemokinesis) of neutrophils in uniform concentrations of fMLP and IL-8. Cells are migrating on substrata consisting of serum protein (serum), fibrinogen (Fbgn), fibrinogen and ICAM-1 (Fbgn+ICAM), or fibronectin (Fn). (A) Chemotactic index of cells migrating in uniform concentrations of fMLP and IL-8. (B) Speed of migration in uniform concentrations of fMLP and IL-8. (C) Tracks plotting the migration of ten representative cells in uniform concentrations of fMLP (left) and IL-8 (right). Scale is in µm. Results are shown as mean±s.e.m., n=5. No statistical differences were observed (Student's t-test).
