In recent years, calcium titanate (CaTiO 3 ) and carbon‐containing materials have gained much attention in a number of biomedical material researches. To maximize the advantages of both materials, we developed a novel alkoxide method to get “calcium titanate with calcium carbonate” (CaTiO 3 –CaCO 3 ). The objective was to evaluate the crystallinity and elemental composition of CaTiO 3 –CaCO 3 prepared by alkoxide method, CaTiO 3 – a C elaborated by modified thermal decomposition method, commercially‐prepared CaTiO 3 , and the effect of these materials on the bone marrow stromal cell. Hydroxyapatite was used as positive control material. We examined the cellular proliferation, osteoblastic differentiation, and mineralization of KUSA/A1 cells cultured with the materials. The results showed that CaTiO 3 –CaCO 3 and CaTiO 3 – a C contained evidence of calcium carbonate enhancing cell proliferation, osteoblastic differentiation, and mineralization. On the contrary, the commercially‐prepared CaTiO 3 revealed absence of calcium carbonate with lower cell response than the other groups. The results indicated that calcium carbonate could play a key role in the cell response of CaTiO 3 material. In conclusion, our findings suggest that CaTiO 3 –CaCO 3 could be considered an important candidate as a biomaterial for medical and dental applications. © 2009 Wiley Periodicals, Inc.
