Tissue slices from IBD patients exhibited IBD‐typical characteristics, including immune cell infiltrates and elevated secretion of known IBD‐related biomarkers, such as IL‐8, calprotectin, IL‐17A, and IFN‐γ, which were preserved in our ex vivo culture [40, 41, 42, 43]. Here, CXCL8 is linked to inflammatory bowel disease.
