Stem cells offer the potential for regeneration of lost tissue in neurological 
disease, including multiple sclerosis (MS). Their development in vitro and their 
use in vivo in animal models of degenerative neurological disease and recent 
first efforts in human clinical trials were the topics of a recent international 
meeting sponsored by the Multiple Sclerosis International Federation and the 
National Multiple Sclerosis Society on "Stem Cells & MS: Prospects and 
Strategies" Participants reviewed the current state of knowledge about the 
potential use of stem and progenitor cells in MS and other degenerative 
neurological disorders and outlined a series of urgent fundamental and applied 
clinical research priorities that should allow the potential of regeneration of 
damaged tissue in MS to be assessed and pursued.
