骨髓间充质干细胞移植治疗脊髓损伤的研究现状

目的近年来,在神经外科领域,人们对骨髓间充质干细胞移植治疗脊髓损伤进行了一些有益的尝试,就其有关的研究进展加以综述.资料来源应用计算机检索medline 1990-01/2004-11关于脊髓损伤研究方面的相关文章,检索词"mesenchymal stem cells,transplantation,spinal cord injury",并限定文章语言种类为"English".同时检索中文生物医学文献数据库1990-01/2004-10有关骨髓间充质干细胞移植治疗脊髓损伤的文章,限定文章语言种类为中文,检索词"骨髓间充质干细胞,移植,脊髓损伤".资料选择对资料进行初审,选取与骨髓间充质干细胞移植治疗脊髓损伤进展有关的文献,对剩余的文献开始查找全文,选取最新进展性文献纳入研究.资料提炼共收集到27篇关于骨髓间充质干细胞移植治疗脊髓损伤的文献,排除重复或类似的同一研究,19篇符合本研究要求.资料综合针对骨髓间充质干细胞移植治疗脊髓损伤的问题,对所检索出文献中的众多观点进行提炼综合.发现骨髓间充质干细胞可作为填充物填补损伤部位,定向再生为神经细胞锚靠周围组织完成上行下传功能的重建,移植时创造抑制胶质细胞再生、保护神经细胞胞体存活、促进自体神经细胞再生的微环境.还重点介绍了国内外已经成功的经验,并提出最有希望的展望.结论骨髓间充质干细胞可在损伤脊髓中存活、向损伤部位迁移并向神经元和星形胶质细胞分化,促进损伤脊髓功能的恢复,可能是治疗脊髓损伤的一条有效途径.

Transplantation of bone marrow derived mesenchymal stem cells for treatment of spinal cord injury

OBJECTIVE: In recent years, in the field of neurosurgery, people have tried to study the mesenchymal stem cells(MSCs) transplantation for treatment of spinal cord injury and review its related studies.DATA SOURCES: We did a computer-search of Medline for spinal cord injury related articles published in English from January 1990 to November 2004, with the key words of "mesenchymal stem cells, transplantation,spinal cord injury". Meanwhile, We also searched Chinese Biomedical Literature Database (CBM) for bone marrow-derived mesenchymal stem cells for transplantation of spinal cord injury related articles published from January 1990 to November 2004, with the key words of "mesenchymal stem cells, transplantation, spinal cord injury" in Chinese.STUDY SELECTION: All articles were selected firstly, and those relevant to progression of mesenchymal stem cells transplantation in spinal cord injury therapy were collected. The full texts of the rest literatures were looked up and the latest evolutional articles were enrolled.DATA EXTRACTION: A total of 32 articles about the mesenchymal stem cells transplantation in spinal cord injury therapy were collected. After the exclusion of repetitive or similar studies, 19 articles met our criteria.DATA SYNTHESIS: Aiming at the spinal cord injury therapy by means of mesenchymal stem cells transplantation, the viewpoints of collected articles were summarized. We found bone marrow derived mesenchymal stem cells could supply lesioned part as filler. Directional regeneration accomplishes the construction of the function that transfers up and down for the nerve cell anchor through surrounding structure. The microenvironment which can inhibit the regeneration of the glial cell, protect the survival of nerve cell body, promote the regeneration of autogenic nerve cells shall be created in transplant. The international successful experience was introduced emphatically, and the most hopeful outlook was suggested.CONCLUSION: The transplanted MSCs survive, migrate to the injury site and differentiate into neurons and astrocytes. Transplantation of MSCs following spinal cord injury may improve the recovery of spinal function and may be an effect way in treating spinal cord injury.
