Research Abstract

Our research goal was to clone the gene that transforms Caco-2 cells into M cells, which transcytose antigenic molecules in the intestinal lumen to subepithelial immune cells, by employing the Caco-2/Raji cells co-culture system. While we tried to find optimal condition for the induction of M cell phenotype, reproducible condition was not identified. Moreover, the transfection efficiency of Caco-2 cells by a lipofection method was too low to perform expression cloning.
