There is a lack of effective means of promoting remyelination of the central nervous system (CNS) in humans with chronic demyelinating disease. We have investigated the ability of transplanted glia to myelinate areas of the CNS equivalent to focal demyelinated lesions in multiple sclerosis (MS). In these studies we show that transplantation of oligodendrocytes or their progenitors into the CNS of a neonatal or adult canine myelin mutant results in repair of large areas similar in size to many MS plaques. Progenitor or pre-progenitor cells of the oligodendrocyte lineage have the greatest capacity for myelination following grafting, although cells of neonatal origin may also be used. Such an approach may therefore have therapeutic value in the repair of focal lesions in human myelin disease.
