The sprouting of neurites from a neuron represents a highly specialized form of cellular morphogenesis that must involve coordinated changes in two major cellular processes at two membrane locations: reorganization of the cytoskeleton and redirection of membrane traffic from the trans-Golgi network to the plasma membrane of the growth tip. How exactly are these two processes linked and how is spatial and temporal coordination achieved at the first instance of neurite sprouting? Recent advances may have already revealed some, if not most of the pieces in the puzzle. We discuss below, with some extrapolations, of what has recently come to light, and what more is needed to construct a coherent picture. (C) 2002 Elsevier Science (USA). All rights reserved.
