Eosinophil motility on PN. Paths of purified blood eosinophils migrating in the presence (A and C) or absence (B and D) of IL-5 (10 ng/ml) on full-length PN coated at 5 μg/ml (A and B) or FBS alone (C and D) were revealed by perturbation of a monolayer of 1 μm diameter latex beads. Wells were photographed after 20 hours. Bar, 100 μm. (E) Morphometric analysis of track areas as a function of PN coating concentration. Data shown are means (±SEM) of two wells, representative of experiments with three donors.
