✦ Synopsis
Transplantation repair of demyelinating lesions is restricted because relatively few cells can be introduced at only a limited number of sites. Repair could be enhanced by stimulating division of transplanted cells and by directing migration to multiple or distant lesions. This article demonstrates that transplanted oligodendroglial progenitors proliferate more when co-grafted with growth factor-secreting cells, yet retain the capacity to form myelin. Transplanted glial cells also migrate preferentially toward the growth factor-secreting cells when the two are implanted at separate sites. This opens avenues to examine growth factor actions on glia in vivo and improves the prospects for human remyelination therapies.
