文题释义:
胶原蛋白:是生物高分子材料,为动物结缔组织的主要成分,是哺乳动物体内含量最多、分布最广的功能性蛋白,占蛋白质总量的30%左右;具有良好的生物相容性、低免疫原性和组织可降解吸收性,在创面止血、愈合,缺损组织的填充、修复及重建,药物载体和组织工程等方面有广泛应用,是理想的医用生物材料。
医用生物材料:是用来对生物体进行诊断、治疗、修复,或替换其病损组织、器官及增进其功能的材料,包括金属、陶瓷、高分子、复合材料等。
 
 
背景:胶原蛋白因具有低免疫原性,良好的生物相容性和生物降解性,在医用生物材料方面得到广泛应用。
目的:综述近年来国内外胶原蛋白的来源、生物活性、改性及其在医用生物材料方面的应用进展。
方法:通过计算机检索2010至2018年PubMed、Elsevier、Springerlink、中国知网等数据库发表的相关文章,英文检索词为“collagen,crosslinking,immunogenicity,biocompatibility,tissue engineering”,中文检索词为“胶原蛋白,交联,免疫原性,生物相容性,组织工程”。

结果与结论:胶原蛋白主要从动物肌腱、皮肤、尾巴等组织中提取获得的,具有良好生物相容性、低免疫原性和降解性等特性,但缺乏足够的机械强度。交联改性或与其他生物材料复合使用均可改善胶原蛋白的机械性能。目前,胶原蛋白已被广泛应用于止血剂与创面敷料、生物补片、骨修复材料、药物释放载体及作为组织工程支架等方面;临床使用显示,胶原蛋白对缺损组织的修复、再生及重建有着显著促进作用。

Abstract:

BACKGROUND: Collagen has been widely used as a medical biomaterial due to its low immunogenicity, good biocompatibility and biodegradability.

OBJECTIVE: To summarize the sources, bioactivity, modification of collagen and its application as a medical biomaterial in recent years.
METHODS: The first author searched related articles in PubMed, Elsevier, Springerlink, and CNKI from 2010 to 2018. The key words were “collagen, crosslinking, immunogenicity, biocompatibility, tissue engineering” in English and Chinese, respectively.

RESULTS AND CONCLUSION: Collagen is mainly extracted from animal tendon, skin, tail and other soft tissues. It has low immunogenicity, good biocompatibility and biodegradability, but has insufficient mechanical strength. Crosslinking modification or combination with other biomaterials can both improve the mechanical properties of collagen. Nowadays, collagen is widely used as hemostatic and wound dressing, biological repair patches, bone repairing materials, drug release carriers and tissue engineering scaffolds, which has a significant role in the clinical repair, regeneration and reconstruction of tissue defects.
