Research Abstract

We have reported that transplantation of neural stem/progenitor cells(NS/PCs) for spinal cord injury promoted functional recovery, while the precise mechanism of functional recovery still remains unclear. In the present study, we utilized NS/PCs derived from genetically myelin deficient shiverer mutant mice. We compared shiverer mouse derived NS/PCs with wild type mouse derived NS/PCs. We have shown that graft-derived re-myelination is significant in the functional recovery after neural stem/progenitor cell transplantation after spinal cord injury.
