Abstract:

BACKGROUND: It is a hotspot that calcium phosphate and calcium sulphate as the main ingredients are combined with one or more other materials to improve or increase the performance of bone tissue engineering scaffolds.
OBJECTIVE: To introduce the research advance of these two kinds of scaffolds in bone tissue engineering.
METHODS: The articles related to the bone tissue engineering published during January 2000 to June 2015 were retrieved from CNKI and PubMed databases by computer. The key words were “bone tissue engineering, scaffold, calcium phosphate, calcium sulphate, vascularization” in Chinese and English, respectively.
ESULTS AND CONCLUSION: Calcium phosphate and calcium sulfate are characterized as having good biocompatibility, biodegradability, osteoconductivity and complete bone substitutability. However, single use of calcium phosphate or calcium sulfate scaffold has certain disadvantages, both of which are difficult to fully meet the requirements of the bone defect repair. Improvement can be acquired in the mechanical strength, injectability and biodegradability, as well as drug-loading and pro-angiogenesis of the scaffold in combination with other materials. In the basal and clinical research, we should explore and develop ideal scaffolds in on the basis of therapeutic aim. However, most of the scaffold studies are still at the extracorporeal and animal experiment stage, and the comparative studies on composite scaffolds and optimal proportion of those composite scaffolds still need to be further investigated.
