Intestinal stem cells are specialized cells located in the lining of the intestine that play a crucial role in maintaining the health of the digestive system. They have the unique ability to divide and differentiate into various types of cells, such as enterocytes, goblet cells, and Paneth cells, which are essential for nutrient absorption and protection against pathogens. These stem cells are primarily found in structures called crypts within the intestinal epithelium. They continuously regenerate the intestinal lining, which is important because the cells in the intestine have a short lifespan and are constantly being shed and replaced. This regenerative capacity helps to ensure proper digestion and overall gut health.
