Review: LGR5 and Intestinal Stem Cells

Since the discovery of LGR5 as a marker of intestinal stem cells, we have learned a great deal about the intestinal crypt stem cell niche. In the August issue of Gastroenterology Bon-Kyoung Koo and Hans Clevers review the discovery of crypt base columnar cells as LGR5+ adult stem cells and

How do Intestinal Stem Cells get their Wnt?

Intestinal homeostasis and stem cells are not affected when Paneth cells stop producing Wnt, but Wnt is required to maintain the stem cell niche in intestinal epithelial cultures, according to a mouse study in the December issue of Gastroenterology. These findings indicate that underlying mesenchymal cells provide a secondary physiological
