Research Abstract |
A cultivation system was designed to evaluate piezoelectric effects of the BaTiO_3 (BTO) ceramics on bone marrow cells, and rat bone marrow cells seeded on surfaces of the BTO ceramics were cultured in culture medium. ALP activity on the charged BTO surface was slightly higher than that on the non-charged BTO surface. The amount of calcium on the charged BTO surface was also higher than that on the non-charged BTO surface. These results showed that the electric charged BTO surface enhanced osteogenic differentiation.
