The protocol of Ulcerative Colitis Zebrafish Modeling using Dextran sodium sulfate(DSS,Colitis Grade)

The use of zebrafish Danio rerio as a model for intestinal damage is well established and the dextran sodium sulfate (DSS)-induced zebrafish IBD model mimics different features of mammalian IBD phenotypes, including neutrophilic inflammation in the intestine, excessive mucus production, increased intestinal lymphangiogenesis and upregulation of pro-inflammatory cytokines and markers ccl20, il1β, il23, il8, mmp9 and tnf-α[1].

1.1 Animal Model

3dpf(days post fertilization) Zebrafish

1.2 Material

DSS(Yeasen#60316ES,MW36000-50000)、AB-PAS(Yeasen#60534ES)

1.3 Protocol

  • Zebrafish embryos were obtained from natural spawning and raised until 1 day post fertilization (dpf) in an incubator at 28.5℃ in recirculating water (60 μg/mL instant ocean sea salts) and supplemented with methylene blue up to 1 dpf;
  • After 1 dpf, use E3 embryo culture medium without methylene blue to culture to 3 dpf;
  • Prepare 10% DSS storage solution with E3 medium;
  • Dilute DSS with culture medium to the maximum non lethal dose (DSS concentration reference: 0.5%);
  • The zebrafish was treated with 0.5% DSS from 3 dpf to 6 dpf, and the indexes were observed.

2 Results

The successful indicators of modeling: the number of neutrophils increased, acidic mucin increased, and the expression of inflammatory factors increased.

  • Number of neutrophils: the number of neutrophils increased and moved to the intestine and epithelium;
  • Acid mucus protein: It was verified by paraffin pathological section and AB-PAS staining method that the acid mucus protein in zebrafish intestine increased after DSS immersion;
  • Inflammatory factor expression: The expression of inflammatory factor in zebrafish intestine increased after DSS treatment[1,2].
