Abstract
Ulcerative colitis (UC) is an idiopathic, chronic inflammatory disorder of the colonic mucosa, and its etiology remains unclear. Animal models are commonly used to study UC, including the murine model of colitis induced with dextran sulfate sodium (DSS). The murine model of DSS-induced colitis is well appreciated and widely used because of its simplicity, cheapness and high success rate. DSS-induced colitis has many similarities to human UC in location, clinical and histological features. In view of its indispensable position in the study of UC, we provide a brief overview of the animal model of DSS-induced colitis in terms of its features, modelling methods, pathogenesis and influencing factors.
