    摘要: Demineralized bone matric (DBM) and native bone morphogenetic protein (nBMP) are complex mixtures of non-collagenous bone proteins. These mixtures contain many of the BMPs that are available as recombinant molecules. Information regarding the presence in these materials of molecules that may affect the availability and activity of the BMPs is very limited. A chemical extraction of DBM, such as using alkali-urea produces a water soluble extractate which inhibits the osteogenic activity of DBM. Noggin, an extracellular BMP ligand antagonist is found in the water soluble extractate from DBM. Differential chemical extraction is a useful means of removing non-osteogenic, or osteogenic inhibitory molecules from DBM and nBMP.

    摘要: The use of autogenous bone graft is the current gold standard in the 1.5 million bone-grafting surgeries performed annually in the United States. Although this practice has resulted in high rates of fusion success, it is associated with increased operative time and blood loss, along with a significant degree of donor-site morbidity. Additionally, in certain settings such as revision cases, multilevel constructs, or in patients with medical comorbidities, autogenous bone graft may exist in limited quantity and quality. This significant need for a suitable alternative to autogenous bone graft has stimulated great interest in the exploration of bone graft substitutes and extenders.
