To sum up, we first conclude that we can isolate mesenchymal stem cells from human fetal articular cartilage and they can be induced to differentiae into several cells under appropriate induction conditions. Anymore, they have their original tissue speciality. Therefore, we first report that mesenchymal stem cells of articular cartilage origin are superior to mesenchymal stem cells of bone marrow origin as seeding cells of cartilage tissue engineering and we provide a kind of new seeding cells of cartilage tissue engineering for the future clinic application.
