Spatially controlled rhBMP-2 mediated calvarial bone formation in a transgenic mouse model.


PMID 28847606

Abstract

The study aimed to investigate the localized osteogenic activity of recombinant human bone morphogenetic protein (rhBMP-2), when delivered using enzymatically crosslinkable injectable glycol chitosan hydrogel. A critical sized bilateral calvarial defect model was used wherein one defect was implanted with rhBMP-2 loaded hydrogel (HPP-GC+BMP). The neighboring defect was implanted with an osteoconductive, collagen hydroxyapatite matrix "Healos
