The gastric epithelium is the lining of the stomach that is composed of specialized cells and tissues responsible for secreting mucus, enzymes, and other substances involved in digestion. Research on the gastric epithelium focuses on understanding its structure, function, and regulatory mechanisms, as well as its role in health and disease, such as gastritis, gastric ulcers, and gastric cancer. Studies in this area may involve investigating cellular interactions, signaling pathways, genetic mutations, and potential therapies for gastric conditions. Understanding the gastric epithelium is essential for advancing our knowledge of digestive processes and developing effective treatments for gastrointestinal disorders.
