TLDR
Wnt is part of a signaling loop that affects homeostasis of intestinal stem and Paneth cells in mice, and Wnt3 signaling is required for growth and development of organoid cultures, whereas nonepithelial Wnt signals could provide a secondary physiological source of Wnt.

In vitro expansion of single Lgr5+ liver stem cells induced by Wnt-driven regeneration

TL;DR: Findings indicate that previous observations concerning Lgr5+ stem cells in actively self-renewing tissues can also be extended to damage-induced stem Cells in a tissue with a low rate of spontaneous proliferation.

An integral program for tissue renewal and regeneration: Wnt signaling and stem cell control

TL;DR: The widespread importance of Wnt signaling in driving tissue renewal has been revealed by the identification of Axin2 and Lgr5, genes expressed in cells that are responding to Wnt signals, and this crucial role in stem cell self renewal is reviewed.

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.

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.

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.

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.
