Abstract:
After culture expansion of mesenchymal stem cells (MSCs) from a few milliliter of fresh patient’s bone marrow, we applied the MSCs on alumina ceramic ankle prosthesis and further cultured in an osteogenic medium for 2 weeks. After the culture, the MSCs differentiated into osteoblasts, which fabricated bone matrix on the surface of ceramic prosthesis. The expansion of MSCs followed by osteogenic differentiation was done using the commercially available medium with some chemicals and patient’s own serum. The MSCs well proliferated and differentiated into osteoblasts, even the MSCs were from old aged (more than 70 years old) patients. The tissue engineered ceramic prostheses were implanted into osteoarthritic patients. Typical X-ray findings showed that radiodense areas began to appear around the cell-seeded areas on the prosthesis about 2 to 3 months after the operation. These findings confirmed the importance of tissue engineering approach for early bone fixation and the approach can be done using small number of bone marrow cells and patient’s own serum without adding animal-derived products.
