摘要:

文题释义:

组织工程支架:目前干细胞移植已被证明可以促进脊髓损伤后的神经元再生,但是存在移植细胞存活率、定植率较低等局限性。组织工程支架可以提供一个三维空间,模拟更有利的内源性微环境,为移植干细胞提供有效支持,从而促进干细胞在体内黏附、迁移和分化。

间充质干细胞:是一种多能干细胞,它具有干细胞的所有共性,即自我更新和多向分化能力。它又具有其他干细胞所没有的优势如易于分离提取、不存在伦理问题、不存在免疫排斥风险等,目前已成为组织工程技术中较为常用的种子细胞。

 

摘要

背景:干细胞具有多向分化潜能,组织工程支架可以为其提供支持,神经营养因子则可以促进干细胞的分化,3者联合移植治疗方案促进脊髓损伤功能恢复是当前研究热点之一。

目的:综述近年来干细胞、组织工程支架、神经营养因子及其联合移植治疗脊髓损伤的研究进展。

方法:作者检索PubMedSciencedirectMedline、中国知网等数据库20001月至201910月的相关文章。英文检索词为“spinal cord injurymesenchymal stem cellsissue engineeringneurotrophic factor,中文检索词为脊髓损伤,间充质干细胞,组织工程,神经营养因子,检索文献类型为研究原著,初检文章712篇,再经过严格筛选后,对符合要求的79篇文献进行分类综述。

结果与结论:单纯的干细胞移植并不能重建脊髓的复杂结构和稳定性,而单纯的生物材料、神经营养因子也不能替代脊髓损伤过程中的神经元丢失,因此联合移植是脊髓损伤治疗的研究方向。但是由于脊髓损伤的部位、损伤的组织及其修复时的营养需求各异,如何将干细胞、组织工程支架、神经营养因子联合的方案最优化仍是一个巨大的挑战。

Abstract:

BACKGROUND: Stem cells have multi-directional differentiation potential. Tissue engineering scaffolds can provide support for them. Neurotrophic factors can promote the differentiation of stem cells. The combination of the three therapies to promote the functional recovery of spinal cord injury is one of the current research hotspots.

OBJECTIVE: To review the research progress of stem cells, tissue engineering scaffolds, neurotrophic factors and their combined transplantation in the treatment of spinal cord injury in recent years.

METHODS: The authors searched PubMed, ScienceDirect, Medline, and CNKI for original articles from January 2000 to October 2019. The key words were “spinal cord injury, mesenchymal stem cells, issue engineering, neurotrophic factor” in English and Chinese, respectively. Totally 712 studies were retrieved. After strict screening, 79 studies that met the requirements were classified and reviewed.



RESULTS AND CONCLUSION: Stem cell transplantation alone cannot reconstruct the complex structure and stability of the spinal cord. Biological materials or neurotrophic factors alone cannot replace the loss of neurons during spinal cord injury. Therefore, combined transplantation is the research direction of spinal cord injury treatment. However, due to the differences in the location of spinal cord injury, the tissue of injury and the nutritional requirements of its repair, the characteristics of various stem cells, tissue engineering scaffolds and neurotrophic factors are different. How to optimize the combination of the three is still a huge challenge.
