Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is carried out in patients with IBD and healthy subjects requiring ileocolonoscopy as part of routine care (disease monitoring or polyp/colon cancer screening). It aims the generation and culturing of organoids from digestive biopsies recovered from healthy and/or pathological (inflammatory) ileal and/or colonic mucosa during an ileo-colonoscopy. These cultures will make it possible to validate the organoid production method used in the context of the research (primary objective). In a second phase (secondary objectives), the study will aim to setup a screening tool by irradiating the organoids (step one) and then evaluate in vitro the regenerative activity of treatments dedicated to improve inflammatory bowel diseases and acute radiation enteritis (step two).
