A University of Wisconsin-Madison researcher said he would ask federal regulators Friday to approve the first clinical trial injecting special stem cells into the spinal cords of people with the degenerative nerve ailment called Lou Gehrig’s disease. The trial would test whether a technique anatomy professor Clive Svendsen has pioneered on rats afflicted with the disease is safe to use on people. If successful, Svendsen said a much larger clinical trial aimed at treating the disease could be under way in two or three years.
