The development of a long-term intestinal culture system has, until recently, eluded researchers. Here the authors describe a method allowing long-term culture of both small intestine and colon that incorporates an air-liquid interface coupled with a three-dimensional matrix scaffold. The cultures show epithelial cell proliferation and multilineage differentiation to the major cell types and accurately recapitulate the Wnt- and Notch-dependent intestinal stem cell niche.
