What does the Steel City have to do with stem cell arthritis treatment?



One of the leading basic researchers involving stem cells and osteoarthritis is Dr. Rocky Tuan, the director of the Center for Cellular and Molecular Engineering at the University of Pittsburgh Medical Center. Dr Tuan and his colleagues have modified electrospinning, a technique borrowed from the textile industry to create a scaffold of polymer nanofibers. Essentially, they have taken fibers and created a unique type of scaffold. They then sprayed mesenchymal stem cells onto these fibers and implanted them into a pig model of osteoarthritis and produced cartilage repair.
This is a brilliant model that shows promise for humans as well. The key of course is to provide a protective environment for mesenchymal stem cells to survive in the hostile environment of an osteoarthritic knee.
