Inflammatory bowel disease (IBD) comprises a group of intestinal disorders, including ulcerative colitis and Crohn’s disease. Intestinal fibrosis, as result of chronic inflammation, is a common complication in IBD. High treatment failure rates associated with existing interventions indicate a high unmet need for more effective drugs to improve the management and outcomes of IBD. Consequently, translational animal models of IBD demonstrating chronic, progressive colonic fibrosis are important tools in preclinical drug discovery for IBD.
