摘要:

背景:骨髓间充质干细胞作为一种多能干细胞在股骨头坏死治疗中的应用越来越多,而单纯干细胞移植及注入往往效果不佳,联合支架材料或其复合物可更好地发挥作用。
目的:综述骨髓间充质干细胞联合载体治疗股骨头坏死的临床及实验研究现状,并展望发展前景。
方法:以“股骨头坏死、骨髓间充质干细胞、载体或支架材料;osteonecrosis of the femoral head,avascularnecrosis, bone marrow mesenchymal stem cells,carrier or scaffold material”为检索词,应用计算机检索1989至2013年中国知网及PubMed数据库关于骨髓间充质干细胞及其载体在股骨头坏死治疗方面的临床及实验文献报道,归纳综述各种载体的特性及局限性。
结果与结论:理想的载体可促进及诱导骨髓间充质干细胞修复股骨头的能力,现有的载体种类繁多,包括自体松质骨、异体骨、天然生物材料、有机材料、生物陶瓷、纳米材料等,各有利弊。所以人们通过将材料复合的手段来寻找理想的载体和支架材料,但仍有一些问题需要深入研究与解决,如支架材料来源没有统一的生产标准、规格及公认的制作方法;如何控制及避免支架植入后的免疫反应及炎症反应;如何保证降解速率与股骨头区域的骨与软骨生成速率一致;如何全面的检测植入后的细胞毒性、生物相容性及治疗效果等。

Abstract:

BACKGROUND: With the development of stem cell research and regenerative medicine, a growing number of technique applications of bone marrow mesenchymal stem cells have been used for treatment of femoral head necrosis. Simple grafting and injection of bone marrow mesenchymal stem cells has a poor effect, which is combined with scaffold materials as cells carrier plays a better role.
OBJECTIVE: To review the research progress of bone marrow mesenchymal stem cells and carriers in the treatment of femoral head necrosis and to look into the future development prospects.
METHODS: A computer-based online search of PubMed (1989/2013) and CNKI (1989/2013) was performed for articles with the key words “osteonecrosis of the femoral head, avascularnecrosis, bone marrow mesenchymal stem cells, carrier or scaffold material” in English and Chinese, respectively. The advantages and limits of various carries and scaffolds were summarized. 
RESULTS AND CONCLUSION: Ideal carriers can promote and induce ability of bone marrow mesenchymal stem cells to repair the femoral head. There is a variety of existing carriers, including autologous cancellous bone, allograft bone, natural biological materials, organic materials, bio-ceramic, nano-materials. Since each material has its own advantages and limitations, composite materials have begun to be used in searching for ideal carriers and scaffolds, and there are however still some issues that remain to be solved, such as lacking of unified standard of production, specification and making process; how to control and prevent the immune response and inflammation after implantation; how to ensure that the degradation rate of scaffold matches the generation rate of bone and cartilage in the femoral head; and how to identify the cytotoxicity, biocompatibility and therapeutic effects after implantation.
