骨髓间充质干细胞治疗股骨头坏死的评价

背景：股骨头坏死的治疗方法很多,但目前还没有满意的方法能促进坏死股骨头的修复。近年来,骨髓间充质干细胞移植治疗早期股骨头坏死缺的了一定的效果。 目的：综述骨髓间充质干细胞在股骨头坏死治疗中的应用进展及存在的问题。 方法：应用计算机检索PubMed数据库、万方数据库及CNKI中国知网数据库1999至2012年相关文献,选择骨髓间充质干细胞的分离、培养、分化、细胞标记及体内示踪研究,骨髓间充质干细胞移植治疗股骨头坏死的基础及临床研究,共纳入39篇文献进行综述。 结果与结论：目前骨髓间充质干细胞的分离方法有贴壁筛选法、密度梯度离心法、流式细胞仪分离法和免疫磁珠分选法;常用的细胞标记及示踪法有同位素示踪法、抗原标记法、抗原标记法、荧光染料标记法和MRI对比增强剂标记法。骨髓间充质干细胞治疗股骨头坏死的方法有髓芯钻孔减压联合骨髓间充质干细胞注射移植治疗股骨头坏死、介入加骨髓间充质干细胞治疗股骨头坏死、基因转染骨髓间充质干细胞移植治疗股骨头坏死、骨髓间充质干细胞的组织工程技术治疗股骨头坏死。虽然近年来对骨髓间充质干细胞移植治疗股骨头缺血坏死的研究取得了很大进展,但仍存在不少问题需要进一步研究。

Evaluation of bone marrow mesenchymal stem cells for the treatment of osteonecrosis of femoral head

BACKGROUND: There are various methods for the treatment of osteonecrosis of femoral head, but there is no satisfactory method to promote the repair of osteonecrosis of femoral head. In recent years, bone marrow mesenchymal stem cell transplantation for the treatment of osteonecrosis of femoral head has achieved certain effect. OBJECTIVE: To review the application progress and problems of bone marrow mesenchymal stem cell transplantation for the treatment of osteonecrosis of femoral head. METHODS:A computer-based online search was performed in PubMed database, Wanfang database and CNKI database for the related articles from 1999 to 2012. The articles on the isolation, culture, differentiation, labeling and in vivo tracing of bone marrow mesenchymal stem cells were selected, as well as the basic and clinical researches on bone marrow mesenchymal stem cell transplantation for the treatment of osteonecrosis of femoral head. A total of 39 articles were included for review. RESUTLS AND CONCLUSION: At present, the method for the isolation of bone marrow mesenchymal stem cells includes adherence screening method, density gradient centrifugation, flow cytometry separation and magnetic activated cell sorting method; the commonly used method for cell labeling and tracing includes isotope tracing method, antigen labeling method, antigen labeling, fluorescent labeling and MRI contrast enhancer labeling method. The method for the treatment of osteonecrosis of femoral head with bone marrow mesenchymal stem cells includes pith drilling decompression combined with bone marrow mesenchymal stem cell injection and transplantation, intervention plus bone marrow mesenchymal stem cell transplantation, gene transfection combined with bone marrow mesenchymal stem cell transplantation and tissue engineering technology of bone marrow mesenchymal stem cells. Although, the research on the bone marrow mesenchymal stem cell transplantation for the treatment of osteonecrosis of femoral head has achieved great progress, there are still problems needed to be further solved.
