Advanced Science, EarlyView.The immunocompetent Intestine‐on‐a‐Chip (IoC) is developed using melt electrowritten (MEW) half‐pipes. Intestinal epithelial cell (IEC) culture is optimized in the MEW‐based IoC, followed by co‐culture with monocyte‐derived dendritic cells (moDCs) and T cells in 3D hydrogels.
