Abstract

Introduction: Chronic inflammation of the intestinal epithelium is an underlying cause of the two main types of inflammatory bowel disease (IBD), ulcerative colitis (UC), and Crohn's disease (CD). Ex vivo organoids derived from the intestinal epithelium are a useful model to study IBD. Whether such cultures can be established from surgically resected diseased IBD intestinal tissues has not been fully explored. In this study, we tested our ability to establish organoids from nondiseased and diseased IBD intestinal tissues. Materials and methods: From 12 UC patients (n = 54 tissues) and 20 CD patients (n = 49 tissues), tissues were collected from multiple colonic regions, and for CD, the terminal ileum was also surveyed. Organoids were cultured in Matrigel domes using defined media. In primary tissues, we conducted immunohistochemical analysis for mucin 2 (MUC2) and Alcian blue staining for goblet cells. Organoids were stained for Ki67, E-cadherin, and MUC2. Results: For UC, we were highly successful establishing organoids from nondiseased tissue (n = 12 of 13, 92%). This success rates dropped from tissues with mild (n = 6 of 9, 67%), moderate (n = 2 of 9, 22%), or severe disease (n = 1 of 23, 4%). The rates from nondiseased CD tissues were reduced (n = 11 of 23, 48%) in comparison to such tissues from UC patients. In UC, goblet cells and MUC2 were reduced in diseased tissues and these phenotypes were retained in organoids. Conclusions: Organoids can be readily derived from nondiseased surgically resected IBD tissues. While more work is needed to improve their derivation from diseased tissue, our study supports the use of organoids to study IBD pathophysiology.
