Abstract

We describe how axonal differentiation during neuronal growth is dependent on intracellular transport. The interaction of diffusion and active transport of a morphogen whose concentration at the neurite tips influences the growth rate can lead to an instability involving winner-take-all growth, forming a single, quickly growing neurite (the axon) and inhibiting the growth of the other neurites. We discuss the dynamics of this process and its dependence on cell parameters.
