  • Publication number: 20190358366
    Abstract: An embodiment includes therapeutic compositions that include a hydrogel medium and a plurality of tissue segments dispersed within the medium. The hydrogel medium preserves and stores the tissue through processing, transport, and storage. The embodiment addresses an identified problem of preserving a tissue, whether such tissue is fresh, cryopreserved, or sterile. The therapeutic compositions may be placed on or within the body to cover and protect wounds, provide a scaffold for reconstruction, repair, or replacement, and reduce surgical complications as a result of inflammation and scar tissue formation. Other embodiments are described herein.
