Objective: Motilin is a proximal small intestinal hormone with roles in gastrointestinal motility, gallbladder emptying and hunger initiation. The molecular mechanisms underlying motilin release in response to fats, bile and duodenal acidification are poorly understood, in part due a lack of suitable cellular and rodent models. We therefore generated a novel human intestinal organoid model with fluorescently labelled motilin-expressing M-cells, which we used to establish the k...
