This protocol details the establishment of enteroids, a three-dimensional intestinal model, from fetal intestinal tissue. Immunofluorescent imaging of epithelial biomarkers was used for model characterization. Apical exposure of lipopolysaccharides, a bacterial endotoxin, using microinjection technique induced epithelial permeability in a dose-dependent manner measured by the leakage of fluorescent dextran.
