Yale team treats primates with Parkinson’s

A Yale University research team said it was able to successfully treat some symptoms of primates with severe Parkinson’s disease by injecting them with human neural stem cells. The possibility of a similar treatment being used on humans is still years away, however, the team said. The primates were better able to walk, move and eat, and had diminished tremors, said the team at Yale, which worked with researchers at Harvard, the University of Colorado and the Burnham Institute. The study, conducted on a total of eight primates, demonstrated the effect stem cells could have on counteracting abnormalities in other cells, researchers said.
