That said:
"In the small intestine, stem cells in the crypts generate new absorptive, goblet, enteroendocrine, and Paneth cells, replacing most of the epithelial lining of the intestine every week. The diverse fates of the stem-cell progeny are controlled, in part at least, by the Notch signaling pathway, while the Wnt pathway is required to maintain the stem-cell population."
