文题释义:
组织工程技术:是指通过利用种子细胞和支架材料复合,然后移植入体内,在外源的细胞因子的作用下促进种子细胞的定向分化,从而在局部再生起到修复损伤部位的作用。
原位组织工程技术:又称原位诱导再生技术,是指不需要外来的种子细胞,通过利用生物支架材料本身的理化性质与体内微环境相互作用,来诱导自体细胞的迁移、黏附,实现缺损组织的原位再生。
原位组织工程技术的特点:利用自体细胞特别是干细胞进行组织修复,避免了体外分离培养种子细胞的繁琐过程,并且避免了体外培养种子细胞容易污染的缺点;该过程不添加外源性种子细胞,因此极大程度地避免了免疫排斥反应;通过一定的手段使原位细胞迁徙到病变部位,从而达到修复的效果,该过程更加接近于人体损伤组织的自我修复,将生物体视为完整的生物反应器,这样的修复效果或许是更佳的。
 
摘要
背景:原位组织工程技术较传统的组织工程技术有明显的优势,在促进组织再生和骨、软骨修复方面具有较好的效果。
目的:综述原位组织工程技术在骨与软骨修复中的应用及存在的问题。
方法:应用计算机检索CNKI数据库、PubMed数据库及Elsevier数据库中发表的相关文献,中文检索词为“原位组织工程技术,骨,软骨,骨缺损,软骨修复,组织工程”,英文检索词为“in situ tissue engineering,bone,cartilage,bone defects,cartilage repair,tissue engineering”,选择2000年1月至2018年11月收录的原位组织工程技术在骨和软骨损伤修复中应用的相关文章,包括综述、基础及临床研究。
结果与结论:原位组织工程技术是在传统组织工程技术基础上发展起来的一种用于再生和修复的技术,应用于骨损伤修复取得了良好的成绩,其不依赖外源种子细胞,通过各种新型支架材料并利用其自身特有的结构和理化性质,募集受损部位周边的干细胞迁徙到损伤部位,完成骨损伤的原位修复。原位组织工程技术为软骨损伤修复提供了新的思路和方向,在软骨损伤修复中具有全新应用价值,其主要是利用植入的支架材料来诱导局部微环境,诱导周边细胞迁移到病损部位而发挥修复作用。

Abstract:

BACKGROUND: In situ tissue engineering technology has obvious advantages compared with the traditional tissue engineering technology and exhibits good effects in promoting tissue regeneration and bone/cartilage repair.

OBJECTIVE: To review the application and problems of in situ tissue engineering technology in bone/cartilage repair
METHODS: A computer-based search of CNKI, PubMed, and Elsevier was performed for relevant articles concerning the application of in situ tissue engineering in the field of bone and cartilage repair published from January 2000 to November 2018. The keywords were “in situ tissue engineering, bone, cartilage, bone defects, cartilage repair, tissue engineering” in Chinese and English, respectively. The article types were review, basic and clinical studies.
RESULTS AND CONCLUSIONS: In situ tissue engineering technology is a technology developed for regeneration and restoration based on traditional tissue engineering technology, which has achieved good results in the repair of bone injury. It does not rely on exogenous seed cells and has the ability to repair bone damage by various new scaffold materials which possesses unique structure and physicochemical properties. These scaffold materials can recruit stem cells around the damaged site to migrate to the injured site and complete the in situ repair of bone damage. In situ tissue engineering technology provides new ideas and directions for cartilage damage repair, and has new application value in cartilage injury repair. The main purpose is to use the implanted scaffold material to induce the local microenvironment, and induces the peripheral cells to migrate to the lesion site to play a repairing role.

Key words: in situ tissue engineering technology, bone, cartilage, repair, tissue engineering, scaffold materials, cytokine, in situ repair of injury
