Detaljert beskrivelse
Primary and secondary objectives:
Main Objective: Characterize morphologically, molecularly and functionally the MSCs of colon and small intestine of patients with IBD and compared to MSCs of colon and small intestine of control patients.
Secondary objectives: To study the reaction of colon and small intestine MHC in patients with IBD following stimulation with bacterial compounds.
Methodology:
Clinical study exploratory translational physiopathological. Two groups of patients with Crohn's disease and ulcerative colitis who require colonoscopy or surgery for intestinal resection will be included. These two groups will be compared to a control group consisting of patients requiring colonoscopy for screening or intestinal resection for colorectal cancer or diverticulum.
Intestinal sampling by biopsy during the colonoscopy or with surgical specimen during the surgery will be performed to isolate the MSCs.
The outcome measures will be a qualitative and quantitative analysis of MSCs by immunohistochemistry, immunofluorescence, cell proliferation and differentiation, production of pro- and anti-inflammatory cytokines in the basal state and after bacterial stimulation.
Total of 60 patients (20 in groups, 15 with colonoscopy and 5 with surgical specimens).
