摘要: [摘要] 近年来,因肿瘤、创伤、发育畸形、感染等原因造成骨缺损的修复材料包括自体骨或异体骨、人工合成材料、生物活性材料。然而,这些材料因取骨量限制、免疫排斥、成骨活性低、支架降解等问题一直困扰着临床医生。理想的骨缺损材料应具备三个要素,募集种子细胞、缓释生长因子、提供模拟微环境的支架。随着骨组织工程不断发展,脱细胞外基质材料(decellularuzed Extracellular Matrix,dECM)作为生物活性支架材料因其无免疫源性、良好的成骨性能、缓释生长因子、促进种子细胞的粘附、干性的维持等优点而倍受关注。本文围绕脱细胞外基质材料(dECM)在骨再生中的应用及研究进展作一综述。

Abstract: Abstract: Recently,the restoration of bone defect,caused by tumor、trauma、malformation、infection and so on,include auto or allogenic bone、synthetic material and bioactive material.However,the mentioned above materials are still bothering clinicians due to its limited acquired bone volume、immunological rejection、lower osteogenic property and scaffold degradation.And the perfect biomaterial should equip the following three key factors:recruiting seeding cell、slow-releasing growth factors、and serving as mimicking microenvironment scaffold.With the rapidly advancement of bone engineering,dcellularized extracellular matrix(dECM) as bioactive scaffold materials,attributed to freeing of immunogenicity、ideal osteogenic property、slowing-releasing growth factors、promoting adhesion of seeding cell and even maintaining stem property of seeding cell,is arousing widely interests.This paper maks a review aiming at the application and research progress of decellularized extracellular matrix scaffold material in bone regeneration.
