Abstract

An in vitro microfluidic intestine on-chip is described herein that mimics the structure and at least one function of specific areas of the gastrointestinal system in vivo. In particular, a multicellular, layered, microfluidic intestinal cell culture, which is some embodiments is derived from patient's enteroids-derived cells, is described comprising L cells, allowing for interactions between L cells and gastrointestinal epithelial cells, endothelial cells and immune cells. This in vitro microfluidic system can be used for modeling inflammatory gastrointestinal autoimmune tissue, e.g., diabetes, obesity, intestinal insufficiency and other inflammatory gastrointestinal disorders. These multicellular-layered microfluidic intestine on-chips further allow for comparisons between types of gastrointestinal tissues, e.g., small intestinal duodenum, small intestinal jejunum, small intestinal ileum, large intestinal colon, etc., and between disease states of gastrointestinal tissue, i.e. healthy, pre-disease and diseased areas. Additionally, these microfluidic gut-on-chips allow identification of cells and cellular derived factors driving disease states and drug testing for reducing inflammation.
