An investigation by journalists revealed that more than 200 clinics in Arizona are offering unapproved and unregulated stem cell treatments. Reporters found some clinics staffed with people who lacked proper medical training to work with stem cells or treat certain medical conditions. The article cites earlier revelations in research by David Brafman and Emma Frow, Fulton Schools assistant professors of biological and health systems engineering. They found some clinics using stem cell treatments not proven to cure or provide relief from diseases. Brafman and Frow concluded that when businesses claim to treat a wide variety of conditions it is less likely the health care providers at the businesses have been fully trained in the areas in which they are practicing.
