Summary: The limited axonal growth after central nervous system (CNS) injury such as spinal cord injury presents a major challenge in promoting repair and recovery. The literature in axonal repair has focused mostly on frank regeneration of injured axons. Here, we argue that sprouting of uninjured axons, an innate repair mechanism of the CNS, might be more amenable to modulation in order to promote functional repair. Extrinsic inhibitors of axonal growth modulate axon sprouting after injury and may serve as the first group of therapeutic targets to promote functional repair.
