The gastrointestinal epithelium provides the first line of defense against invading pathogens, among which Helicobacter pylori is linked to numerous gastric pathologies, including chronic gastritis and cancer. Primary gastric epithelial cells represent a useful model for the investigation of the underlying molecular and cellular mechanisms involved in these H. pylori associated diseases. In this chapter, we describe a method for the isolation of primary gastric epithelial cells from mice and detection of epithelial cell adhesion molecule (EpCAM) expression in the isolated cells.
Keywords: EpCAM; Gastric epithelial cells; Helicobacter pylori; Primary culture.
