The present invention relates to a method for preparing a biocompatible porcine cartilage-derived extracellular matrix membrane capable of adjusting an in-vovo degradation rate and a mechanical property, and a composition containing the porcine cartilage-derived extracellular matrix as an active ingredient, for preventing adhesion between tissues and/or organs. Despite its high biocompatibility as a natural material, cartilage tissue extracellular matrix has a short decomposition period and its mechanical property is weak, thereby restricting the application. Accordingly, a method of enhancing the mechanical property through physical or chemical treatment and radiation treatment has been developed. In the present invention, biomaterials of various formulations were produced by treating the porcine cartilage-derived extracellular matrix with physiochemical methods. In addition, although was carried out, a characteristic that the above cartilage-specific function was maintained despite the treatment of the physico-chemical treatment was checked. Furthermore, it may also be used as an adhesion inhibitor with excellent in-vivo stability and anti-adhesion effect by using the porcine cartilage-derived extracellular matrix material. |
