Research Abstract

To analyze the interaction of oral bacteria and intestinal epithelia cells, the aim of this study is to establish a intestinal epithelial cell line containing Paneth cells which secrete α -defensins. In conventional monolayer cell culture, intestinal epithelial cells were observed, however, Paneth cells were not identified. Next, organoid culture were performed by using mouse intestinal crypts. It was analyzed whetherobtained organoids were maintaining the function of a Paneth cell.
