Abstract: Disclosed herein are flowable tissue matrix compositions comprising small pieces of partially or completely decellularized tissue suspended in a gelatinized tissue or gelatin gel comprising partially or completely decellularized tissue or synthetic gelatin. The flowable tissue matrix compositions can contain factors that promote or enhance native cell migration, proliferation, and/or revascularization after implantation into a subject. Also disclosed are methods of making and using the flowable tissue matrix compositions. The compositions can be implanted into a tissue in need of repair, regeneration, healing, treatment, and/or alteration, and can promote or enhance native cell migration, proliferation, and/or revascularization.
Abstract: Disclosed herein are tissue treatment products that have been bound to at least one chelating agent. Also disclosed are tissue treatment products that have been functionalized with at least one metal and/or at least one metal-binding protein. The tissue treatment products can have antimicrobial properties and/or factors that promote or enhance native cell migration, proliferation, and/or revascularization after implantation into a subject. Also disclosed are methods of making and using the tissue treatment products. The tissue treatment products can be implanted into a tissue in need of repair, regeneration, healing, treatment, and/or alteration and can promote or enhance native cell migration, proliferation, and/or revascularization.
