Some of the diseases and conditions specifically listed by Johnson — such as multiple sclerosis, Parkinson’s disease, strokes, chronic obstructive pulmonary disease, heart disease, emphysema, autism, chronic pain and fatigue — are not approved by the FDA to be treated using stem cell therapy, according to a July 22 post on the FDA’s website.
