文题释义:

组织工程建立历史:组织工程学建立的历史可回溯到20世纪80年代,美国Joseph P. Vacanti和Robert Langer教授首先提出组织工程研究探索,并在美国《科学》杂志撰文发表其研究成果。组织工程这一术语是由著名美籍华裔科学家Y. C. Fung教授提出,在1987年被美国国家科学基金委员会确定。在组织工程发展的历史过程中,科学家应用组织工程技术在裸鼠上成功地形成了具有皮肤覆盖的人耳郭形态软骨,是一项重大的突破。裸鼠背上的耳朵标志着组织工程技术可以形成具有复杂三维空间结构的组织器官,显示了组织工程从基础迈向临床应用的广阔前景。
软骨:是胚胎早期的主要支架成分,随着胎儿发育逐渐被骨取代,取代过程一直延续到出生后一段时期。是特化的致密结缔组织,细胞间质坚固而有弹性。在成体内,仅散在分布一些软骨,其作用依所处部位而异。

 

背景:各种原因引起的运动性软骨损伤非常常见,由于软骨自愈能力欠佳,其损伤后的修复一直以来都是一大难题。

目的:综述组织软骨构建过程中不同类型种子细胞的特点,探讨体外组织工程软骨的构建在修复运动性软骨损伤中的应用。

方法:检索PubMed,万方及CNKI数据库与组织工程化软骨修复运动性软骨损伤,以及组织工程化软构建中干细胞和支材料应用相关的文章。共检索到文献190篇,排除重复性研究,最终纳入47篇进行综述。
结果与结论:骨髓间充质干细胞在不同诱导条件下可以向软骨细胞分化,与脂肪间充质干细胞和脐带间充质干细胞相比,具有更好的软骨细胞分化潜能,但其安全性还待进一步研究。良好的支架材料不仅可以诱导干细胞的分化,也是软骨构建的成功与否的关键,复合材料是今后支架材料研究的发展方向。

Abstract:

BACKGROUND: Sports-induced cartilage injury is very common; due to the poor self-healing capacity of the cartilage, cartilage repair has always been a difficult problem.
OBJECTIVE: To review the features of different seed cells in tissue-engineered cartilage construction and to explore the application of tissue-engineered cartilage construction in the repair of sports-induced cartilage injury in vitro.
METHODS: We searched PubMed database, Wanfang database and CNKI database for articles related to tissue-engineered cartilage repair of sports-induced cartilage injuries, as well as stem cells and scaffold materials used in tissue-engineered cartilage construction. Totally 190 articles were retrieved, and finally 47 articles were included in result analysis after repetitive studies were excluded.
RESULTS AND CONCLUSION: Bone marrow mesenchymal stem cells under different conditions can differentiate into chondrocytes, and have better potential of chondrogenic differentiation compared with adipose-derived mesenchymal stem cells and umbilical cord-derived mesenchymal stem cells. But, their safety still needs to be further studied. Good scaffolds cannot only induce stem cell differentiation, but also be the key to cartilage construction. Composite materials are the future direction of the scaffold research.
