Performing tissue repair with stem cells typically requires applying copious amounts of growth factor proteins -- a task that is very expensive and becomes challenging once the developing material is implanted within a body. A team of 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 ...
