In this study, human induced pluripotent stem (iPS) cell-derived colon organoids (hiPSC-COs) were treated with a combination of tumor necrosis factor alpha (TNF-α), interferon-gamma (IFN-γ), and interleukin (IL)-1β (3 cytokines [3CK]), known to be elevated in the serum of IBD patients. Here, TNF is linked to inflammatory bowel disease.
