Transplantation of glial cells into the CNS

Glial cell transplantation into the CNS offers an experimental approach to help us unravel the complex interactions that occur between CNS glia, Schwann cells and axons during repair and development. This article reviews recent advances that have been made in our understanding of the nature and potential of CNS repair using this approach, and introduces the idea of using transplantation to address broader issues in glial biology.
