摘要： The invention provides fibrin-based, biocompatible materials useful in promoting cell growth, wound healing, and tissue regeneration. These materials are provided as part of several cell and tissue scaffolding structures that provide particular application for use in wound-healing and tissue regenerating. Methods for preparing these compositions and using them are also disclosed as part of the invention. A variety of peptides may be used in conjunction with the practice of the invention, in particular, the peptide IKVAV, and variants thereof. Generally, the compositions may be described as comprising a protein network (e.g., fibrin) and a peptide having an amino acid sequence that comprises a transglutaminase substrate domain (e.g., a factor XIIIa substrate domain) and a bioactive factor (e.g., a peptide or protein, such as a polypeptide growth factor), the peptide being covalently bound to the protein network. Other applications of the technology include their use on implantable devices (e.g., vascular graphs), tissue and cell scaffolding. Other applications include use in surgical adhesive or sealant, as well as in peripheral nerve regeneration and angiogenesis.

摘要： Proteins are incorporated into protein or polysaccharide matrices for use in tissue repair, regeneration and/or remodeling and/or drug delivery. The proteins can be incorporated so that they are released by degradation of the matrix, by enzymatic action and/or diffusion. As demonstrated by the examples, one method is to bind heparin to the matrix by either covalent or non-covalent methods, to form a heparin-matrix. The heparin then non-covalently binds heparin-binding growth factors to the protein matrix. Alternatively, a fusion protein can be constructed which contains a crosslinking region such as a factor XIIIa substrate and the native protein sequence. Incorporation of degradable linkages between the matrix and the bioactive factors can be particularly useful when long-term drug delivery is desired, for example in the case of nerve regeneration, where it is desirable to vary the rate of drug release spatially as a function of regeneration, e.g. rapidly near the living tissue interface and more slowly farther into the injury zone. Additional benefits include the lower total drug dose within the delivery system, and spatial regulation of release which permits a greater percentage of the drug to be released at the time of greatest cellular activity.
摘要翻译：将蛋白质掺入用于组织修复，再生和/或重塑和/或药物递送的蛋白质或多糖基质中。可以掺入蛋白质，使其通过降解基质，通过酶作用和/或扩散来释放。如实施例所示，一种方法是通过共价或非共价方法将肝素与基质结合，形成肝素基质。然后肝素将肝素结合生长因子非共价结合到蛋白质基质上。或者，可以构建融合蛋白，其包含交联区域，例如因子XIIIa底物和天然蛋白质序列。当需要长期药物递送时，例如在神经再生的情况下，在基质和生物活性因子之间引入可降解的键可能是特别有用的，其中期望在空间上改变作为再生的功能的药物释放速率，例如快速靠近生物组织界面，并进一步向进入损伤区更慢。额外的益处包括递送系统内的总药物剂量越少，释放的空间调节，允许在最大的细胞活动时释放更多百分比的药物。

摘要： Bioactive molecules are entrapped within a matrix for the controlled delivery of these compounds for therapeutic healing applications. The matrix may be formed of natural or synthetic compounds. The primary method of entrapment of the bioactive molecule is through precipitation of the bioactive molecule during gelation of the matrix, either in vitro or in vivo. The bioactive molecule may be modified to reduce its effective solubility in the matrix to retain it more effectively within the matrix, such as through the deglycosylation of members within the cystine knot growth factor superfamily and particularly within the TGFβ superfamily. The matrix may be modified to include sites with binding affinity for different bioactive molecules, for example, for heparin binding.

摘要： Supplemented matrices comprising a PTH releasably incorporated therein, optionally containing a granular material, which are used to heal bone fractures, particularly bone fractures with a risk of becoming delayed unions or non-unions, are described herein. The PTH is incorporated either through covalent linkage to the matrix or through non-covalent interaction with the matrix and/or the granules. These supplemented matrices decrease the time of healing compared to autograft and or trigger healing of bone fractures which otherwise would not heal. The matrices are biocompatible, preferably biodegradable, and can be formed in vitro or in vivo, at the time of implantation. The PTH may be a part of a fusion peptide. PTH can be incorporated into the matrices with full retention of its bioactivity. PTH can be releasably incorporated in the matrix.
