摘要：
beta-TCP, as one of calcium phosphates ceramics, exerts perfect biocompatibility and osteoconductivity, and is clinically used as a bone graft substitute for decades. Consequently, the effects of beta-TCP ceramics on intracellular Ca2+ concentration, mineralization of osteoblast and BSA protein structure were studied. Results showed that beta-TCP could increase the intracelluar Ca2+ concentration and mineralization of osteoblast, indicating that beta-TCP ceramics could take part in the organic metabolism and the degradation product had no detrimental effect on osteoblast in vitro. Furthermore, beta-TCP ceramics could increase the content of alpha-helix and beta-pleated sheet and change BSA into more ordering structure, those changes might be favorable for the biomineralization after beta-TCP ceramics implanted.
