    摘要: Osteoinductive compositions and implants having increased biological activities, and methods for their production, are provided. The biological activities that may be increased include, but are not limited to, bone forming; bone healing; osteoinductive activity, osteogenic activity, chondrogenic activity, wound healing activity, neurogenic activity, contraction-inducing activity, mitosis-inducing activity, differentiation-inducing activity, chemotactic activity, angiogenic or vasculogenic activity, and exocytosis or endocytosis-inducing activity. In one embodiment, a method for producing an osteoinductive composition comprises providing partially demineralized bone, treating the partially demineralized bone to disrupt the collagen structure of the bone, and optionally providing a tissue-derived extract and adding the tissue-derived extract to the partially demineralized bone. In another embodiment, an implantable osteoinductive and osteoconductive composition comprises partially demineralized bone, wherein the collagen structure of the bone has been disrupted, and, optionally, a tissue-derived extract.

    摘要: In one embodiment, the method comprises providing tissue, preparing the tissue, and treating the tissue to improve remodeling characteristics of the tissue. The tissue may be, for example, cortical bone. Treating the tissue to improve remodeling characteristics may comprise heating the tissue, treating the tissue with a chemical, or other. Heating the tissue may be done in the absence of oxygen and may comprise heating the tissue in a vacuum, heating the tissue in an inert atmosphere, heating the tissue in a reducing atmosphere, coating the tissue with a protective coating and heating the tissue, or other. Further embodiments comprise treating the tissue in supercritical fluids, for example, to dry or virally inactivate the tissue.
