Zusammenfassung:The purpose of the present invention is to provide: detergent-free decellularization method of xenogenic biological tissues for human body surgery, in which the pericardium, blood vessels, other membrane-like biological tissues, and the like are decellularized so as to have resistance to mechanical property loss, mineralization and immune reactivity; and decellularized tissue. Decellularized tissue, according to the present invention, when compared to untreated tissue, has greater calcification reduction in vivo, blood compatibility and biocompatibility improvement, tissue thickness reduction, and increases in tensile strength, kink resistance and the like. La présente invention concerne: un procédé de décellularisation sans détergent de tissus biologiques xénogènes pour la chirurgie du corps humain, dans lequel le péricarde, les vaisseaux sanguins, d'autres tissus biologiques de type membrane et analogues sont décellularisés de manière à avoir une résistance à la perte de propriétés mécaniques, à la minéralisation et à la réactivité immunitaire; ainsi qu'un tissu décellularisé. Le tissu décellularisé selon la présente invention, par rapport aux tissus non traités, présente une plus grande réduction de calcification in vivo, une compatibilité sanguine et une amélioration de biocompatibilité, une réduction d'épaisseur tissulaire et des augmentations de résistance à la traction, de résistance au pliage et analogues. 본 발명은 심낭, 혈관 및 다른 막 유사 생체 조직 등을 무세포화 처리하여, 역학적 성질의 손실, 무기화 및 면역 반응성에 내성을 갖도록 하는, 인체 수술을 위한 이종 생체 조직의 무세제 무세포화 처리방법 및 무세포화 처리된 조직을 제공하고자 한다. 본 발명에 따라 무세포화 처리된 조직은 처리되지 않은 조직보다 생체 내에서 석회화가 감소하고, 혈액적합성 및 생체적합성이 향상되며, 조직의 두께가 감소하고, 인장 강도 및 꼬임 저항 등이 증가하는 우수한 효과가 있다.
