description Organs-on-chips are microfluidic devices for culturing living cells in micrometer sized chambers in order to model physiological functions of tissues and organs. Engineered patterning and continuous fluid flow in these devices has allowed culturing of intestinal cells bearing physiologically relevant features and sustained exposure to bacteria while maintaining cellular viability, thereby allowing study of inflammatory bowl diseases. However, existing intestinal cells do not possess all physiologically relevant subtypes, do not possess the repertoire of genetic variations, or allow for study of other important cellular actors such as immune cells. Use of iPSC-derived epithelium, including IBD patient-specific cells, allows for superior disease modeling by capturing the multi-faceted nature of the disease. Cette invention concerne des organes sur puces sous forme de dispositifs microfluidiques pour la culture de cellules vivantes dans des chambres à l'échelle micrométrique permettant de modéliser les fonctions physiologiques de tissus et d'organes. Un écoulement de fluide structuré et continu modifié dans ces dispositifs a permis la culture de cellules intestinales portant des caractéristiques physiologiquement pertinentes et leur exposition prolongée à des bactéries, tout en conservant la viabilité cellulaire, permettant ainsi l'étude des maladies inflammatoires de l'intestin. Toutefois, les cellules intestinales existantes ne possèdent pas tous les sous-types physiologiquement pertinents, ne possèdent pas le répertoire des variations génétiques, ou permettent l'étude d'autres acteurs cellulaires importants tels que les cellules immunitaires. L'utilisation d'un épithélium dérivé d'iPSC, y compris de cellules spécifiques de patients MII, permet une meilleure modélisation de la maladie par capture de sa nature multi-facettes.
