Amyotrophic Lateral Sclerosis (ALS, also known as Lou Gehrig's Disease) motor neurons created from induced Pluripotent Stem (iPS) cells made from the skin cells of an 83-year-old ALS patient. iPS cells gives scientists an opportunity to study ALS in affected human motor neurons and other patient-derived brain cells.
