Doctors injected stem cells from 8-week-old fetal tissue into the spine of a man in his early 60s who has advanced ALS, or amyotrophic lateral sclerosis. It was part of a clinical trialdesigned to determine whether it is safe to inject stem cells into the spinal cord and whether the cells themselves are safe.
