Abstract:
In rat embryonic dorsal root ganglion explants stimulated by nerve growth factor, the neuron-specific phosphoprotein B-50 (GAP43) is primarily localized in the distal portion of outgrowing neurites. Addition of colchicine leads to a decrease in total amount of B-50 and a marked redistribution in the neurons. The data underscore the role of axonal transport in the concentration of B-50 in growth cones of growing neurites.
