However, one of its most advantageous properties is its ability to spontaneously differentiate into a monolayer of cells with many properties typical of absorptive enterocytes with brush border layer as found in the small intestine.7-fold more potent than doxorubicin and taxol, respectively, while showing about 5., cell viabilities >80%) were used in the digoxin transport assay using a Caco-2 cell monolayer. Functional polarization of Caco-2 cells, the most commonly used model to study intestinal differentiation, is assessed by dome formation and tightness of the monolayer and is under the control of the extracellular matrix (ECM). In vitro cell-based assays are the screening tool of choice for permeability assessment by the pharmaceutical industry, due to the right balance between predictability and ethical issues [1,2]. Therefore, some alternative cell cultures to mimic the human intestinal epithelium, as closely as possible, have been developed to achieve more physiological conditions, as the Caco-2/HT29-MTX coculture and the triple Caco-2/HT29-MTX/Raji B models The mean basal TEER for Caco-2 monolayers was 2605 ± 48 Ω.
