Brief Summary

Over the last decade, the use of mini-organ or organoids has been increasingly developed in fundamental research. Indeed, digestive organoids represent an essential advance compared to classical culture systems (epithelial cell lines, immortalized cells) since they preserve in culture the functional complexity present in vivo (architecture, different cell types). They also have the advantage of being able to be propagated indefinitely (unlike explants), minimizing the use of animal models and reducing the amount of tissue required. Finally, their growth and development depends on the origin of the sample (the organoid will develop differently if the cell source comes from a patient suffering from an inflammatory bowel disease, for example), thus generating models of human pathologies to better determine their physiopathology. The use of organoids in biomedical research has proven to be an indispensable tool for the understanding of cellular and molecular mechanisms involved in epithelial renewal and the screening of molecules and ingredients for applications in the health and agri-food sectors.

Outcome Measures

Primary Outcomes (1)

  • Number of isolated intestinal crypts per biopsies

    Biopsies will be then prepared by isolating intestinal crypts and cultured on a 3D matrix gel (matrigel) with added growth factors reproducing the niche environment of intestinal stem cells, which favors the development of an intestinal epithelium. After intestinal differentiation, organoids will be used for research such as molecular screening, assessment of the effects of intestinal stress and healing.

Secondary Outcomes (4)

  • Number of differentiated organoids

    Day 0

  • Fold change of MUC2 expression

  • Fold change of LGR5 expression

Study Arms (3)

Group Crohn's disease

EXPERIMENTAL

4 additional biopsies for 30 patients with Crohn's disease

Procedure: additional biopsies

Group ulcerative colitis

EXPERIMENTAL

4 additional biopsies for 30 patients with ulcerative colitis

Procedure: additional biopsies

Group No MICI

ACTIVE COMPARATOR

4 additional biopsies for 30 patients out of Inflammatory Disease Chronic Bowel Disease

Procedure: additional biopsies

Interventions

After Verification of eligibility criteria, patient information and consent, digestive biopsies performed for the study are in addition to those performed for the patient's follow-up: * 6 biopsies are taken on average in clinical routine * 4 additional biopsies are necessary to obtain a sufficient number of amplifiable stem cells The samples will be sent within one hour to the Biological Resource Center of the University Hospital of Rennes at room temperature in a tube containing isotonic saline. (CRB). Biopsies will be then prepared by isolating intestinal crypts and cultured on a 3D matrix gel (matrigel) with added growth factors reproducing the niche environment of intestinal stem cells, which favors the development of an intestinal epithelium. After intestinal differentiation, organoids will be used for research such as molecular screening, assessment of the effects of intestinal stress and healing.
