Journal ArticleDOI

Single Lgr5 stem cells build crypt-villus structures in vitro without a mesenchymal niche.

TL;DR: It is concluded that intestinal crypt–villus units are self-organizing structures, which can be built from a single stem cell in the absence of a non-epithelial cellular niche.
Journal ArticleDOI

Identification of stem cells in small intestine and colon by marker gene Lgr5

TL;DR: The expression pattern of Lgr5 suggests that it marks stem cells in multiple adult tissues and cancers, suggesting that it represents the stem cell of the small intestine and colon.
Journal ArticleDOI

Long-term expansion of epithelial organoids from human colon, adenoma, adenocarcinoma, and Barrett's epithelium.

TL;DR: A technology that can be used to study infected, inflammatory, or neoplastic tissues from the human gastrointestinal tract is developed that might have applications in regenerative biology through ex vivo expansion of the intestinal epithelia.
Journal ArticleDOI

Paneth cells constitute the niche for Lgr5 stem cells in intestinal crypts

TL;DR: It is concluded that Lgr5 stem cells compete for essential niche signals provided by a specialized daughter cell, the Paneth cell, in colon crypts, and co-culturing of sorted stem cells with Paneth cells markedly improves organoid formation.
Journal ArticleDOI

Crypt stem cells as the cells-of-origin of intestinal cancer

TL;DR: It is concluded that stem-cell-specific loss of Apc results in progressively growing neoplasia in long-lived intestinal stem cells.
