摘要： Bone matrix compositions having nanoscale textured surfaces and methods for their production are provided. In some embodiments, bone matrix is prepared for implantation and retains nanoscale textured surfaces. In other embodiments, nanostructures are imparted to bone matrix wherein collagen fibrils on the surface of the bone matrix have been compromised, thus imparting a nanoscale textured surface to the bone matrix. Generally, these methods may be applied to mineralized or demineralized bone including partially or surface demineralized bone.

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, mitosisinducing 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： The present invention provides methods of improving the osteogenic and/or chondrogenic activity of a bone matrix, e.g., a dermineralized bone matrix (DBM), by exposing the bone matrix to one or more treatments or conditions. In preferred embodiments the bone matrix is derived from human bone. The treatment or condition may alter the structure of the bone matrix and/or cleave one or more specific proteins. Cleavage may generate peptides or protein fragments that have osteoinductive, osteogenic, or chondrogenic activity. Preferred treatments include collagenase and various other proteases. The invention further provides improved bone and cartilage matrix compositions that have been prepared according to the inventive methods and methods of treatment using the compositions. The invention further provides methods of preparing, testing, and using the improved bone matrix compositions. Ona assay comprises exposing relatively undifferentiated mesenchymal cells to a bone matrix composition and measuring expression of a marker characteristic of osteoblast or chondrocyte lineage(s). Increased expression of the marker relative to the level of the marker in cells that have been exposed to a control matrix (e.g., an inactivated or untreated matrix) indicates that the treatment or condition increased the osteogenic and/or chondrogenic activity of the bone matrix. Suitable cells include C2C12 cells. A suitable marker is alkaline phosphatase. The inventive methods increase the osteogenic and/or chondrogenic activity of human DBM when tested using this assay system.
摘要翻译：本发明提供了通过将骨基质暴露于一种或多种治疗或条件来改善骨基质（例如，矿化骨基质（DBM））的成骨和/或软骨形成活性的方法。在优选的实施方案中，骨基质来源于人骨。治疗或病症可以改变骨基质的结构和/或切割一种或多种特定蛋白质。切割可产生具有骨诱导，成骨或软骨形成活性的肽或蛋白质片段。优选的治疗包括胶原酶和各种其他蛋白酶。本发明进一步提供了根据本发明的方法和使用该组合物进行治疗的方法制备的改进的骨和软骨基质组合物。本发明进一步提供了制备，测试和使用改进的骨基质组合物的方法。 Ona测定包括将相对未分化的间充质细胞暴露于骨基质组合物并测量成骨细胞或软骨细胞谱系特征性标志物的表达。相对于已经暴露于对照基质（例如失活或未处理的基质）的细胞中标记水平的标记表达增加表明治疗或病症增加了骨基质的成骨和/或软骨形成活性。合适的细胞包括C2C12细胞。合适的标记是碱性磷酸酶。当使用该测定系统进行测试时，本发明方法增加人DBM的成骨和/或软骨形成活性。
