Bone repair may be one of the first major applications of tissue engineering; efforts to encourage the growth of new bone using novel matrices, bone morphogenic proteins, gene therapy, and stem cells are all showing promise. But the commercial stakes are so high that some researchers are worried that patent claims, and a reluctance to test competing technologies in combination, could delay progress in the field.
