Doctors encouraged by early-stage trial of MS stem cell therapy

Injecting stem cells into patients' brains found to be safe and could stop further damage from the disease

Doctors are cautiously hopeful about a new multiple sclerosis therapy after finding that injecting stem cells into patients' brains was safe and potentially protective against further damage from the disease.

The small, early stage trial was only able to assess whether injecting cells directly into the brain was well tolerated by patients, but in tests carried out in the year after treatment, researchers found hints that the cells may have a long-lasting, beneficial impact.
