β-Tricalcium phosphate (TCP) is a type of bioceramic material which is commonly used for hard tissue repair and famous of its remarkable biocompatibility and osteoconductivity with similar composition to natural bone. However, TCP lacks osteoindcutive properties. Stromal-derived factor 1α (SDF-1α) can promote bone regeneration with excellent osteoinduction effect. In this study, SDF-1α was loaded into TCP to investigate the in vitro effects of SDF-1α on the osteoinductive properties of TCP. In vitro studies showed that SDF-1α/TCP scaffold significantly stimulated the expression of osteopontin and osteocalcin. As to the in vivo studies, the rabbit bone defect model showed that SDF-1α stimulated more new bone formation. In conclusion, SDF-1α/TCP bioceramic scaffolds could further promote bone regeneration compared to pure TCP bioceramics. |
