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.
