A group of MIT researchers have been developing a new process to enhance the effectiveness of transplanting bone marrow cells to the site of a fracture. While the procedure has been done some 40,000 times, it's often marred by rejection. The new research uses a scaffold to hold epidermal growth factor molecules that can promote the growth and differentiation of stem cells. New research published in Stem Cells suggests that the process improved cell survival and increased proliferation. Further research is being done on animal models. Their goal is direct implantation into patients.
