Neutrophil chemotaxis within the fMLP gradient on fibronectin and on endothelial cells. (a) Motility index (MI) and chemotactic index (CI) of neutrophils on fibronectin (green) and on endothelial cells (blue). (b) Angular distribution of neutrophil movement on fibronectin (circles) and on endothelial cells (triangles) with a value of 1 indicating migration of a cell straight toward fMLP. Each point represents the angular displacement of an individual neutrophil, and the solid bar indicates the average. (c) Average rate of neutrophil migration on fibronectin (green) and on endothelial cells (blue).
