A groundbreaking study from the University of Adelaide reveals potential reversibility of osteoarthritis through a new treatment targeting Gremlin 1 gene-marked stem cells. Existing therapies for osteoarthritis focus on symptom relief, but this research challenges the traditional view and suggests a paradigm shift in treatment. University of Adelaide research shows that treating osteoarthritis by stimulating Gremlin 1 cells in joint cartilage leads to significant recovery and challenges the categorization of the disease as wear and tear.
