The development of functional neuronal networks relies on the spatial accuracy of axon extension. Each extending axon is tipped by a growth cone that can interpret extracellular "guidance cues" and navigate the axon along the correct path. After neuronal networks have been developed, injury to the adult central nervous system induces the formation of barriers to regenerating axons. It is well known that growth cones use similar mechanisms for their navigation during development and regeneration. Our aim is to investigate growth cone navigation with particular emphasis on the roles of guidance cues, intracellular signals, cytoskeleton, adhesion machinery and membrane dynamics. These revelations will help elucidate the fundamental principles of axon tract formation and establish the molecular and cellular biological basis for axon tract repair.
