Research development and prospect of calcium phosphate biomaterials with intrinsic osteoinductivity / 生物医学工程学杂志

ABSTRACT

Calcium phosphates ceramics are frequently used as bone substitute materials in clinics because they are similar to the bone in mineral phase, they are of no antigenicity, and they have good biocompatibility as well as excellent osteoconductivity. The question as to whether calcium phosphate biomaterials possess osteoinductivity has been debated for a long time. Up to now, extensive fundamental studies and clinical application have demonstrated that calcium phosphate ceramics with special structure may induce bone formation in soft tissue. In this paper are reviewed the discovery and confirmation of calcium phosphates ceramics with intrinsic osteoinductivity, the process and mechanism of osteoinduction, and the relationship between osteoinductivity of calcium phosphate materials and animal species, the mesenchymal stem cells related to osteoinduction, the application of osteoinductive biomaterials. The researches directed toward to the osteoinduction of calcium phosphate are prospected.
