文题释义:
肌腱干细胞:
肌腱细胞曾被认为是肌腱中唯一的细胞类型,但近年来肌腱干细胞相继在人类、小鼠、大鼠以及兔的肌腱组织中被发现,打破了这一观念。肌腱干细胞可通过自我更新维持代谢平衡。与其他成人干细胞一样,肌腱干细胞也具有多向分化的潜能,这意味着它不仅可以分化为肌腱细胞,在一定的病理条件下还能转变为非肌腱细胞,包括脂肪细胞、软骨细胞以及骨细胞。肌腱细胞与肌腱干细胞不同,其属于特异性成熟细胞,已不具备分化为其他类型细胞的能力,也不能像肌腱干细胞那样表达干细胞相关基因,如Oct-4、SSEA-1/4 以及nucleostemin 。
韧带:属于致密结缔组织,主要可分为两类:弹性结缔组织和胶原纤维彼此交织成的不规则的致密结缔组织。弹性组织(elastic tissue)是以弹性纤维为主的致密结缔组织。粗大的弹性纤维或平行排列成束,如项韧带和黄韧带。韧带白色带状的结缔组织,质坚韧,有弹性,能把骨骼连接在一起,并能固定某些脏器如肝、脾、肾等的位置。韧带亦称铰合韧带(hinge ligament),为软体动物斧足类的左右两个贝壳的连结物,一般将位于壳顶后方外面的韧带称外韧带。

 

摘要
背景:
有研究报道,前交叉韧带有着在非手术情况下康复的潜力,韧带的某些与细胞修复有关的细胞因子以及干细胞或祖细胞等生物因素影响着前交叉韧带的愈合。
目的:综述间充质干细胞与前交叉韧带损伤治愈联系的相关文献,了解最终分化为前交叉韧带的干细胞/祖细胞的潜力,为利用间充质干细胞治疗前交叉韧带损伤提供依据。
方法:第一作者检索PubMed数据库的相关文献。检索词为“ACL regeneration  stem/progenitor cells mesenchymal stem cells”。查阅近年来相关文献,包括综述、临床研究和基础研究,最终纳入45文献。
结果与结论:近年来,对细胞治疗前交叉韧带损伤以及肌肉骨骼再生有了大量的研究,但是干细胞的使用还远远达不到日常临床治疗的需要,最适宜前交叉韧带再生的干细胞的来源以及它们最合适的注入点仍有待确定。尽管采用间充质干细胞治疗前交叉韧带损伤成功的例子已经在动物模型中报告,但仍然不清楚是否干细胞的营养因子可以改善再生或这些细胞自身可以形成新的组织。

Abstract:

BACKGROUND: Anterior cruciate ligament (ACL) has been reported to hold a self-recovery potential, which may be related to certain cytokines and biological factors, such as stem cells or progenitor cells.
OBJECTIVE: To review the literatures about the relationship between mesenchymal stem cells and ACL injuries, and understand the potential of stem cells or progenitor cells differentiating into ACL, thus providing a basis for the clinical use of mesenchymal stem cells in the treatment of ACL injury.
METHODS: A computer-based online research of PubMed databases was performed to collect articles including reviews, clinical trials and basic studies using the English keywords of “ACL regeneration, stem/progenitor cells, mesenchymal stem cells”. Forty-five eligible articles were included finally.
RESULTS AND CONCLUSION: In recent years, there are a lot of studies addressing the treatment of ACL injuries and muscle/bone regeneration, but the use of stem cells is still far from the clinical requirements. The source of stem cells suitable for the ACL regeneration and their most suitable injection points are under discussion. Although the mesenchymal stem cells have been reported to successfully repair ACL injury in animal models, either trophic factors of stem cells or these cells themselves improving the regeneration remains unclear.
