Regenerating orthopedic tissues within the human body

A team of Duke University biomedical engineers has developed a polymer scaffold for growing cartilage that includes gene therapy vectors to induce stem cells to produce the growth factors they need. The new technique -- biomaterial-mediated gene delivery -- is shown to produce cartilage at least as good biochemically and biomechanically as if the growth factors were introduced in the laboratory.
