Immunocytochemical visualization of trkA and p75 receptors on the growth cones of DRG neurons cultured in 0.05 ng/ml NGF. A, Actin filaments in a growth cone and the edge of a non-neuronal cell (top left) labeled with fluorescein-phalloidin. B, The same cells as inA labeled with 7 μg/ml of the anti-p75 CHEX. The growth cone is strongly labeled, but not the non-neuronal cell.Arrows in A and B indicate filopodia that are labeled by anti-p75. C, Actin filaments in a growth cone and the edge of a non-neuronal cell (top right) labeled with fluorescein-phalloidin.D, The same cells as in C labeled with 25 μg/ml of the anti-trkA CTA. The neurite and growth cone are labeled, but not the non-neuronal cell. Arrows inC and D indicate filopodia that are labeled by anti-trkA. Scale bar, 10 μm.
