Abstract
An embodiment of the present disclosure provides an extracellular matrix-based bioadhesive as an adhesive in the form of a composition including an extracellular matrix-containing hydrogel and a gelatin curing agent, wherein the extracellular matrix-containing hydrogel is gelatinized. Since the extracellular matrix-based bioadhesive according to an embodiment of the present disclosure has the same or similar rheological properties as gelatin, the bioadhesive has flowability at a temperature of 30° C. or higher and may be evenly and easily applied to a lesion site in the body. In addition, the extracellular matrix-based bioadhesive according to an embodiment of the present disclosure may adhere well to the lesion site because of a level of adhesive strength that is about 2 to 6 times higher than that of fibrin glue used as a commercial tissue adhesive. In addition, the extracellular matrix-based bioadhesive according to an embodiment of the present disclosure is based on a tissue-derived extracellular matrix, and thus includes a tissue-derived wound healing component or a tissue regeneration component, and may be used for wound healing or tissue regeneration in addition to bioadhesive applications.
