    摘要: Embodiments of the present invention may include a method for improving handling characteristics of a soft tissue, such as an amnion or muscle tissue. The method may include providing the amnion tissue from a human donor. Furthermore, the method may include exposing the amnion tissue to supercritical carbon dioxide to form an exposed amnion tissue. The exposed amnion tissue may have a higher ultimate tensile strength and elastic modulus than the amnion tissue before the exposure.

    摘要: Methods of preparing biological tissue for bioprosthetic valves include providing fresh biological tissue; treating the tissue with an aqueous cellulose solution for a time sufficient to allow the fluid in the tissue to be replaced by the aqueous cellulose solution; and cross-linking the tissue, wherein the treating step is performed prior to, during, after, or both prior to and after the cross-linking step. The methods may include storing the cellulose-treated and cross-linked tissue in an aqueous solution; or drying the cellulose-treated and cross-linked tissue by a vacuum-drying or lyophilization process, and storing the dried tissue in a dry, ambient environment. The treated tissue may be in the form of a tissue component for a bioprosthetic valve, a valve assembly for a bioprosthetic valve or a fully assembled bioprosthetic valve incorporating the tissue.

    摘要: Provided are compositions and methods for aiding in healing of a tissue wound in an individual. The method generally entail delivering to an individual in need thereof senescent cells such that healing of the wound is accelerated. The disclosure includes use of senescent cells and senescent tumor cells, either of which may be allogeneic or autologous to the individual. Also provided are methods for inducing senescence in cells and using the cells for wound healing, and articles of manufacture comprising senescent cells for use in wound healing.
