    摘要: An osteoinductive demineralized bone matrix, corresponding osteoimplants, and methods for making the osteoinductive demineralized bone matrix are disclosed. The osteoinductive demineralized bone matrix may be prepared by providing demineralized bone and altering the collagenous structure of the bone. The osteoinductive demineralized bone matrix may also be prepared by providing demineralized bone and compacting the bone, for example via mechanical compaction, grinding into a particulate, or treatment with a chemical. Additives such as growth factors or bioactive agents may be added to the osteoinductive demineralized bone matrix. The osteoinductive demineralized bone matrix may form an osteogenic osteoimplant. The osteoimplant, when implanted in a mammalian body, may induce at the locus of the implant the full developmental cascade of endochondral bone formation including vascularization, mineralization, and bone marrow differentiation. The osteoinductive demineralized bone matrix may also be used as a delivery device to administer bioactive agents.

    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.
