MS damage washed away by stream of young blood

A FOUNTAIN of youthful cells reverses the damage found in diseases like multiple sclerosis, a study in mice reveals.

Nerve cells lose their electrically insulating myelin sheath as MS develops. New myelin-generating cells can be produced from stem cells, but the process loses efficiency with age.

Julia Ruckh at the University of Cambridge, and colleagues, have found a way to reverse the age-related efficiency loss. They linked the bloodstreams of young mice to old mice with myelin damage. Exposure to youthful blood reactivated stem cells in the old mice, boosting myelin generation.
