Neural stem cells （NSCs） have high therapeutic potential for reconstruction of the injured spinal cord since they can potentially fnrm neuronal relays to bridge functional con-nectivity between separated spinal cord segments. This requires host axonal regeneration into and connectivity with donor neurons, and axonal growth and connectivity of donor neurons to host central nervous system （CNS） circuitry. In this mini-review, we will discuss key studies that explore novel neuronal relay formation by grafting NSCs in models of SCI, with emphasis on long-distance axonal growth and connectivity of NSCs grafted into in-jured spinal cord.展开更多
