A novel biodegradable bone repair biomaterial of bone-like carbonated apatite with porous structurewas prepared by using self-hardening calcium phosphate cement. Cell culture, degradation in simulated body liq-uid (SBF) and as a carrier for bone morphogenic protein (BMP) controllable releasing experiments were performedto evaluate the biocompatibility, degradation and BMP carrier properties of the porous scaffold. The results revealthat the degradation property of the carbonated apatite is better than hydroxyapatite, the more the content of CO32-in apatite, the faster the degradation of the materials, the cell could attach, proliferate and differentiate on theporous scaffold, indicating that the bone like apatites not only have excellent biocompatibility but are alsobiodegradable and can be used as carriers for BMP controlling release.
