In avulsion injury of the dorsal root, regenerating axons cannot extend through the entry zone, i.e. the transition zone between peripheral and central nervous systems, due to the discontinuity between Schwann cells and astrocytes. We infused neural stem cells through the 4th ventricle in an attempt to enhance axonal growth in injured dorsal roots. Infused stem cells were attached to, and integrated into, the lesion of the root and became associated with axons in the same manner as Schwann cells or perineurial sheath cells in the peripheral nerve, and as astrocytes in the central nerve area. These findings suggest that neural stem cells integrated by infusion through CSF might have a beneficial effect on nerve regeneration by inducing a continuity of Schwann cells and astrocytes at the transition zone.
