Abstract:

Localization of bone morphogenetic protein-2 (BMP-2) with continuous and effective osteogenic stimulation is still a great challenge in bone regeneration. In our study, BMP-2 was tethered upon chondroitin sulfate (CS)-functionalized calcium phosphate cement (CPC) scaffolds via specific noncovalent interactions (in a biomimetic form). The fabricated scaffolds not only controlled the release kinetics and presentation state of rhBMP-2, but also effectively increased the expressions of bone morphogenetic protein receptors (BMPRs) and enhanced the recognitions of remained BMP-2 to BMPRs. In vivo studies demonstrated that BMP-2-loaded CS-functionalized CPC exhibited sustained release of the protein and induced high quality ectopic bone formation. Thus, this work could provide new avenues in mimicking bone extracellular matrix microenvironment and localizing growth factor activity for enhanced bone regeneration.
