Scientists create cartilage scaffold that helps the body regrow bone

Researchers in Sweden have engineered a cell-free cartilage scaffold that can guide the body to rebuild damaged bone. By removing the cells but preserving the structure and natural growth signals, the material acts as a blueprint for the bodys own repair process. In animal studies, it helped regenerate bone without triggering strong immune reactions. The team now plans to scale up production and begin testing the approach in humans.
