Posted: 12/13/2010 - Thirty thousand Americans have ALS or amyotrophic lateral sclerosis, also known as Lou Gehrig's disease. It's a fatal neurodegenerative disease that takes away the ability to walk, talk and eventually even breathe. That quick decline happens within two to five years. There is no known cure. Now, a revolutionary trial is underway to test a new kind of treatment for ALS using human stem cells.
