The approach, based on discoveries in progenitor cell biology from the labs of Bob Langer, Sc.D., at MIT and Jeff Karp, Ph.D., at Harvard Medical School and Brigham and Women's Hospital, utilises small molecules to awaken dormant progenitor cells already in the body and has the opportunity to address numerous degenerative diseases such as hearing loss, demyelinating diseases, skin disorders and gastrointestinal conditions.
