Abstract Source: Springer

The barrier functions of the gastrointestinal tract rely in large part on a single layer of columnar intestinal epithelial cells. These epithelial cells are mediators of intestinal homeostasis, regulating and communicating biochemical signals between underlying stromal cells and luminal cues. The development of representative in vitro models to recapitulate the gastrointestinal epithelium is crucial to understanding cell–cell interactions during intestinal homeostasis and dysfunction. Ideally, models would contain microbiota/immune cells, polarized intestinal architecture, multilayered cellular complexity, extracellular matrix, biochemical cues, and mechanical deformation. This review focuses on historical and state of the art biomaterials and substrates used in the field to establish static and fluidic models of the intestinal epithelium. A discussion of conventional adenocarcinoma colon cancer cell lines, primary intestinal epithelial cells derived from organoids, and stromal support cells such as enteric neurons, myofibroblasts, and immune cells, as well as the importance of increasing cellular complexity and future outlook is included.
