摘要: 目的:检测间充质干细胞表面标记(CD73、 CD90、CD105、CD271和CD34)在人颞下颌关节滑膜间充质细胞(synovial mesenchymal cells,SMCs)上的表达;同时比较这些标记在髁突肥大滑膜无病变和颞下颌关节骨关节病伴关节盘穿孔患者SMCs上表达水平的差异。方法:分别采用多次贴壁培养和组织块法分离得到髂骨骨髓间充质干细胞(mesenchymal stem cells,MSCs)和颞下颌关节原代SMCs并传至3代,应用流式细胞仪检测CD34、CD73、 CD90、CD105、CD271的表达水平。结果:髂骨MSCs及颞下颌关节SMCs表面CD73、CD90、CD105表达量均>90%,CD271表达量<1% ,CD34表达量较低为0.47%~30.00%。结论:髂骨MSCs和颞下颌关节SMCs高表达CD73、CD90、CD105,CD271和CD34表达量较低;CD34在人颞下颌关节骨关节病患者SMCs上的表达量较髁突肥大滑膜无病变患者高。

Abstract: Objective: To detect whether mesenchymal stem cells (MSCs) markers (CD34, CD73, CD90, CD105, CD271) were expressed in synovial mesenchymal cells(SMCs) of temporomandibular joint and to compare their expression in SMCs of temporomandibular joint from human osteoarthritisis and condylar hypertrophy. Methods: SMCs of temporomandibular joint were isolated using explants culture method and MSCs were obtained by the repeated adherent culture method. Then, the third generation cells were characterized and the expression of CD73, CD90, CD105, CD271, and CD34 were qualified by flow cytometry. Results: Fluorescence-activated cell sorting (FACS) analysis showed more than 90% MSCs from human iliac bone and SMCs from human temporomandibular joint expressed CD73, CD90, and CD105, less than 1% cells expressed CD271, and the quantification of CD34 was 0.47%-30%. Conclusion: MSCs from human iliac bone and SMCs of temporomandibular joint from human were positive for CD73, CD90, and CD105, while the expression of CD34 and CD271 were low. SMCs of temporomandibular joint with osteoarthritisis contained more cells positive for CD34 antigens than those from temporomandibular joint condylar hypertrophy.
