    摘要: This invention relates to methods of producing collagen biomaterials by admixing (i) a solution of monomeric collagen, (ii) a solution of polymeric collagen, (ii) cargo particles, and (iv) a non-collagen blocking polymer, to produce a collagen solution. The collagen solution is then allowed to solidify to produce a collagen hydrogel. This may be useful in improving the stiffness of collagen hydrogel constructs and increasing the entrapment and retention of cargo particles.

    摘要: A method is provided for preparing a biological tissue for implantation. The method includes providing a biological tissue from a human or animal donor, treating the biological tissue with an antiviral treatment formulation, lysing the biological tissue, decellularizing the biological tissue with a decellularization treatment formulation, and decontaminating the biological tissue with an alkaline alcohol solution. The antiviral treatment formulation may include a solution of peracetic acid and an alcohol, wherein the peracetic acid is present in the antiviral treatment formulation at a concentration from about 0.03% to about 1.2% (v/v). The decellularization solution may include a solution of a polar aprotic solvent, such as dimethyl sulfoxide, benzyl alcohol and ethanol.

    摘要: The growth factor profile, connective tissue matrix constituents, and immunoprivileged status of urodele extracellular matrix (ECM) and accompanying cutaneous tissue, plus the presence of antimicrobial peptides there, render urodele-derived tissue an ideal source for biological scaffolds for xenotransplantation. In particular, a biological scaffold biomaterial can be obtained by a process that entails (A) obtaining a tissue sample from a urodele, where the tissue comprises ECM, inclusive of the basement membrane, and (B) subjecting the tissue sample to a decellularization process that maintains the structural and functional integrity of the extracellular matrix, by virtue of retaining its fibrous and non-fibrous proteins, glycoaminoglycans (GAGs) and proteoglycans, while removing sufficient cellular components of the sample to reduce or eliminate antigenicity and immunogenicity for xenograft purposes. The resultant urodele-derived biomaterial can be used to enhance restoration of skin homeostasis, to reduce the severity, duration and associated damage caused by post-surgical inflammation, and to promote progression of natural healing and regeneration processes. In addition, the biomaterial promotes the formation of remodeled tissue that is comparable in quality, function, and compliance to undamaged human tissue.
