A Microphysiological System with an Anaerobic Air‐Liquid Interface and Functional Mucus Layer for Coculture of Intestinal Bacteria and Primary Human Colonic Epithelium
Abstract: Coculture of intestinal bacteria with primary human intestinal epithelium provides a valuable tool for investigating host‐colon bacterial interactions and for testing and screening therapeutics. However, most current intestinal model systems lack key physiological features of the in vivo colon, such as both a proper oxygen microenvironment and a mucus layer. In this work, a new in vitro colonic microphysiological system is demonstrated with a cell‐derived, functional mucus that closely resembles the in vivo colonic mucosa and apical microenvironment by employing an anaerobic air‐liquid interface culture. The human primary colon epithelial cells in this new in vitro system exhibit high cell viability (>98%) with ≈100 µm thick functional mucus layer on average. Successful coculture of model anaerobic gut bacterial strains Lactobacillus rhamnosus GG and Anaerobutyricum hallii without loss in human cell viability demonstrates that this new model can be an invaluable tool for future studies of the impact of commensal and pathogenic bacteria on the colon.
