DSS溃疡性结肠炎造模——斑马鱼IBD模型

斑马鱼作为肠道损伤模型的应用已得到充分证实,葡聚糖硫酸钠(Dextran Sulfate Sodium Salt,DSS)诱导的斑马鱼IBD模型模拟了哺乳动物IBD表型的不同特征,包括肠道中性粒细胞炎症、过多粘液生成、肠淋巴管生成增加以及前炎性细胞因子上调。

实验动物
3dpf(days post fertilization) 斑马鱼

 

实验材料
DSS(Yeasen 60316ES,MW:36000~50000)

 

实验步骤
  1. 将斑马鱼胚胎培养在含甲基蓝的E3胚胎培养基中,28.5 ℃,培养至1 dpf;

  2. 1dpf 后使用不含亚甲基蓝的E3胚胎培养基,培养至3 dpf;

  3. 用E3培养基配制浓度为10% DSS的储存液;

  4. 用培养基稀释DSS至最大非致死剂量(DSS浓度参考:0.5%);

  5. 用0.5%的DSS处理斑马鱼,从3 dpf处理到6 dpf,观察指标[1]

     

结果分析
造模成功指标:中性粒细胞数量增多、酸性粘液蛋白增多、炎性因子表达量上升。

 

  1. 嗜中性粒细胞数量:中性粒细胞数量增多,并且向肠和上皮中移动

  2. 酸性粘液蛋白:石蜡病理切片结合AB-PAS染色法验证,DSS浸泡后斑马鱼肠道中酸性粘液蛋白增多

  3. 炎性因子表达量:DSS处理后斑马鱼肠道中炎性因子表达量上升[1,2]

DSS处理组相较于对照组,酸性粘蛋白染色和粘液分泌增加,斑马鱼外周血中的嗜中性粒细胞数量增多并且向肠和上皮中移动,炎性因子表达量显著上调,肠道出现炎症反应。

 

翌圣DSS产品优势

 

翌圣提供高品质DSS(Cat.NO:60316ES,MW:36000~50000),具有以下优势:

 

  1. 高纯度(>98%),硫含量17-19%,游离硫<0.2%,大量数据文献支持,广泛应用于UC模型的构建;

  2. 多种属动物中均可造模:小鼠、大鼠、斑马鱼、猪、果蝇;

  3. 症状表现与人UC极度相似:可用于研究急、慢性结肠炎的发生发展机制,也可用于药物的药效研究;

  4. 简单易行,成模率高,重复性强;

  5. 联合氧化偶氮甲烷 (azoxymethane, AOM)用药,可用于诱发结肠炎相关性癌症 (colitis associated cancer, CAC) 动物模型,成功模拟IBD诱发CAC的过程。
