        1. DSS潰瘍性結(jié)腸炎造?!唏R魚IBD模型

          斑馬魚作為腸道損傷模型的應(yīng)用已得到充分證實,葡聚糖硫酸鈉(Dextran Sulfate Sodium Salt,DSS)誘導(dǎo)的斑馬魚IBD模型模擬了哺乳動物IBD表型的不同特征,包括腸道中性粒細胞炎癥、過多粘液生成、腸淋巴管生成增加以及前炎性細胞因子上調(diào)。

          實驗動物
          3dpf(days post fertilization) 斑馬魚

           

          實驗材料
          DSS(Yeasen 60316ES,MW:36000~50000)

           

          實驗步驟
          1. 將斑馬魚胚胎培養(yǎng)在含甲基藍的E3胚胎培養(yǎng)基中,28.5 ℃,培養(yǎng)至1 dpf;

          2. 1dpf 后使用不含亞甲基藍的E3胚胎培養(yǎng)基,培養(yǎng)至3 dpf;

          3. 用E3培養(yǎng)基配制濃度為10% DSS的儲存液;

          4. 用培養(yǎng)基稀釋DSS至最大非致死劑量(DSS濃度參考:0.5%);

          5. 用0.5%的DSS處理斑馬魚,從3 dpf處理到6 dpf,觀察指標[1]。

             

          結(jié)果分析
          造模成功指標:中性粒細胞數(shù)量增多、酸性粘液蛋白增多、炎性因子表達量上升。

           

          1. 嗜中性粒細胞數(shù)量:中性粒細胞數(shù)量增多,并且向腸和上皮中移動

          2. 酸性粘液蛋白:石蠟病理切片結(jié)合AB-PAS染色法驗證,DSS浸泡后斑馬魚腸道中酸性粘液蛋白增多

          3. 炎性因子表達量:DSS處理后斑馬魚腸道中炎性因子表達量上升[1,2]

          DSS處理組相較于對照組,酸性粘蛋白染色和粘液分泌增加,斑馬魚外周血中的嗜中性粒細胞數(shù)量增多并且向腸和上皮中移動,炎性因子表達量顯著上調(diào),腸道出現(xiàn)炎癥反應(yīng)。

          翌圣提供高品質(zhì)DSS(Cat.NO:60316ES,MW:36000~50000),具有以下優(yōu)勢:

           

          1. 高純度(>98%),硫含量17-19%,游離硫<0.2%,大量數(shù)據(jù)文獻支持,廣泛應(yīng)用于UC模型的構(gòu)建;

          2. 多種屬動物中均可造模:小鼠、大鼠、斑馬魚、豬、果蠅;

          3. 癥狀表現(xiàn)與人UC極度相似:可用于研究急、慢性結(jié)腸炎的發(fā)生發(fā)展機制,也可用于藥物的藥效研究;

          4. 簡單易行,成模率高,重復(fù)性強;

          5. 聯(lián)合氧化偶氮甲烷 (azoxymethane, AOM)用藥,可用于誘發(fā)結(jié)腸炎相關(guān)性癌癥 (colitis associated cancer, CAC) 動物模型,成功模擬IBD誘發(fā)CAC的過程。
