Rodent Neural Progenitor Cells Support Functional Recovery after Cervical Spinal Cord Contusion.

ABSTRACT: Previously, we and others have shown that rodent neural progenitor cells (NPCs) can support functional recovery after cervical and thoracic transection injuries. To extend these observations to a more clinically relevant model of spinal cord injury, we performed unilateral midcervical contusion injuries in Fischer 344 rats. Two-weeks later, E14-derived syngeneic spinal cord-derived multi-potent NPCs were implanted into the lesion cavity. Control animals received either no grafts or fibroblast grafts. The NPCs differentiated into all three neural lineages (neurons, astrocytes, oligodendrocytes) and robustly extended axons into the host spinal cord caudal and rostral to the lesion. Graft-derived axons grew into host gray matter and expressed synaptic proteins in juxtaposition with host neuro
