Atomic force microscopic features of PMCs stimulated with NGF.
A morphologic change of PMCs was examined after incubation for 3 hours with assay medium (A) or 50 ng/mL NGF (B). The mast cell stimulated with NGF reveals a polarized morphology, with membrane extension assuming lamellipodia. Scale: 1 cm = 7.7 μm.
