While there is some indication that cell-based therapies might help treat symptoms and control some urological conditions, researchers says there is a lack of scientific evidence to verify that stem cells are truly effective in these areas and do not cause any unintended harm. In a recent broad study of services offered by stem cell clinics, researchers including Emma Frow, a Fulton Schools assistant professor of biomedical engineering, point out that few of the clinics are using cell treatments for urological problems and that there are no Federal Drug Administration-approved stem cell products for use in urology.
