Small and large intestinal epithelial cell (IEC) lines were established from adult murine intestinal crypts. Both established small and large IECs line (named aMoS7 and aMoC1 respectively) expressed epithelial markers. Similarly to IECs isolated from adult mouse intestines, the expression of major histocompatibility complex (MHC) class II molecules was induced by interferon-γ-treatment in both established cell lines. This expression of MHC class II molecules was higher in small intestinal aMoS7 cells than in large intestinal aMoC1 cells. Treatment with lipopolysaccharide and with ligands of Toll-like receptors 1, 2, 3, and 7 induced secretion of interleukin-6 from both adult IEC lines. These results suggest that the aMoS7 and aMoC1 cell lines can serve as useful tools in analyzing the immunological functions of IECs, especially in studying the IEC response to microbial components and its antigen presenting ability.
