摘要
骨组织工程支架最初用于骨组织的结构性修复,现在负载生物活性物质用于骨诱导和血管形成,促进骨组织生长、修复骨缺损,并呈递生物活性物质。骨组织工程支架负载生物分子或药物等促进成骨和血管生成特性逐渐成为现在研究的热点。在对骨组织工程支架的构建方面,3D打印技术以设计方便,构建不需要模具,可以轻易制备结构复杂、孔隙均匀、几何形态各异的骨组织工程支架,被业内广泛认可。
Bone tissue engineering scaffolds are originally used for structural restoration for bone tissue,and now with the load of biologically active substances they are used for bone induction and angiogenesis to promote bone tissue growth. The bone tissue engineering scaffolds loaded with biological molecules or drugs to promote bone formation and angiogenesis properties has become the research focus in the field. 3D printing technology is widely accepted in the bone tissue engineering field due to the advantages of easy design,easy making of various scaffolds of complex structure,uniform pores and different geometric shapes without molds.
