文题释义:
佐剂性关节炎:是由T细胞介导的慢性、系统性免疫性炎症。关节破坏分为软组织肿胀、骨侵蚀和关节间隙改变3个方面,其临床表现的主要评价指标为关节肿胀数、足爪肿胀度、踝关节病理、足爪X射线摄片等。X射线法诊断观察炎症早期主要表现为关节软组织肿胀,致炎后14-16 d骨质破坏最为显著,软组织肿胀达到高峰,出现关节间隙增宽。
成纤维样滑膜细胞:是介导类风湿关节炎炎症发生的主要细胞,其特征性标记物有波形蛋白、尿二苷磷酸葡萄糖脱氢酶、促衰变因子、血管细胞黏附分子1等。体外原代培养成纤维样滑膜细胞的方法主要有3 种:酶消化法、组织块贴壁法和滑液分离培养法。
摘要
背景:
目前研究者多采用酶消化法从类风湿性患者和佐剂性关节炎大鼠的滑膜组织中分离培养成纤维样滑膜细胞,采用组织块贴壁法体外培养佐剂性关节炎兔成纤维样滑膜细胞较少见。
目的:建立佐剂性关节炎兔成纤维样滑膜细胞的培养方法并观察细胞的生物学特性。
方法:采用多点多次注射佐剂的方法制备佐剂性关节炎兔动物模型,取膝关节滑膜组织,用组织块贴壁法分离培养成纤维样滑膜细胞,观察细胞形态特征。采用CCK-8法检测细胞增殖情况,并用免疫荧光法检测波形蛋白的表达。
结果与结论:倒置显微镜观察原代培养的关节炎兔滑膜细胞形态均为长梭状纤维样,符合成纤维样滑膜细胞的生长特征,且表达波形蛋白的细胞达98%。说明采用组织块贴壁法成功分离培养了佐剂性关节炎兔成纤维样滑膜细胞。

Abstract:

BACKGROUND: Currently, fibroblast-like synoviocytes from the synovial tissue of patients with rheumatoid arthritis or adjuvant arthritis rats are isolated and cultured mainly using enzyme digestion method, but tissue explant adherent method is rarely reported in primary culture.
OBJECTIVE: To establish a culture method of fibroblast-like synoviocytes from adjuvant arthritis rabbits and to investigate cell biological characteristics.
METHODS: Rabbit models of adjuvant arthritis were prepared by injected with adjuvant at multiple sites and times, the knee synovial tissues were obtained, and fibroblast-like synoviocytes were separated and cultured by the tissue explant adherent method. Furthermore, the cell morphology was observed. The cell proliferation was measured using cell counting kit-8 assay, and the expression of Vimentin was detected by immunofluorescence.
RESULTS AND CONCLUSION: The primary cultured rabbit synoviocytes were long spindle fiber-like and coincided with the fibroblast-like synoviocytes. Moreover, cells were positive for Vimentin. In conclusion, fibroblast-like synoviocytes from rabbits with adjuvant arthritis are successfully isolated and cultured by the tissue explant method.
