Mouse severely disabled by a condition similar to multiple sclerosis (MS) could walk less than two weeks following treatment with human stem cells.
When scientists transplanted human stem cells into MS mice, they expected no benefit from the treatment. They thought the cells would be rejected, much like rejection of an organ transplant.
Instead, the experiment yielded spectacular results.
Within a short period of time, 10 to 14 days, the mice could walk and run. Six months later, they showed no signs of slowing down.
