US researchers at Northwestern University in Chicago have for the first time reversed multiple sclerosis symptoms in early stage patients. A dose of their own stem cells “reset” the malfunctioning immune system of 21 patients by using bone marrow stem cell transplants which resulted in a reverse of their disability. Three years after being treated, on average, 17 of the patients had improved on tests of their symptoms, 16 had experienced no relapse and none had deteriorated, the study found. Bloomberg.
