The gastrointestinal epithelium is a highly regenerative organ, where each cell is replaced in a cycle of 4-6 days, depending on the mammalian species. This highly proliferative state is driven by gastrointestinal stem and progenitor cells, located at the base of crypts. These cells give rise to at least six types of differentiated epithelial cells, each with a distinct function in maintaining homeostasis between the intestinal interface and the luminal environment. The isolation and culture of these cells from mammalian gastrointestinal tissue is a novel technique, which allows for the generation and maintenance of an in vitro culture system for adult epithelial cells. There are two predominant methods for isolation and propagation of gastrointestinal epithelial cells, the first is the organoid system developed in 2009, and the second is a later version known as the L-WRN spheroid system. In this chapter, we describe the method to isolate and culture human gastrointestinal stem and progenitor cells and culture them as three-dimensional spheroids using L-WRN cell conditioned media.
