(Submitter supplied) We analyzed gene expression of 3 lines LGR5-GFP, 2 lines KRT20-GFP knock-in colorectal tumor organdies. The cancer stem cell (CSC) theory highlights a self-renewing subpopulation of cancer cells that fuels tumour growth. The existence of human CSCs is mainly supported by xenotransplantation of prospectively isolated cells, but their clonal dynamics and plasticity remain unclear. Here, we show that human LGR5+ colorectal cancer cells serve as CSCs in growing cancer tissues. more...

(Submitter supplied) The gastrointestinal epithelial crypts are clonal units with a high cell turnover, driven by a small population of long-lived, Lgr5-expressing stem cells located in the crypt base. Despite this, depletion of Lgr5+ cells does not lead to severe pathology. Instead, other cell populations, such as secretory and enterocyte precursors are able to de-differentiate, replace Lgr5+ cells, and regenerate the crypt. more...

(Submitter supplied) Lgr5+ stem cells reside at crypt bottoms of the small and large intestine. Small intestinal Paneth cells supply Wnt3, EGF and Notch signals to neighboring Lgr5+ stem cells. While the colon lacks Paneth cells, Deep Crypt Secretory (DCS) cells are intermingled with Lgr5+ stem cells at crypt bottoms. Here, we report Reg4 as a marker of DCS cells. To investigate a niche function, we eliminated DCS cells using the diphtheria-toxin receptor gene knocked into the murine Reg4 locus. more...

(Submitter supplied) The Wnt target gene Lgr5 marks actively dividing stem cells in Wnt-driven, self-renewing tissues such as small intestine and colon, stomach and hair follicles. A 3D culture system allows long-term clonal expansion of single Lgr5+ stem cells into transplantable organoids that retain many characteristics of the original epithelial architecture. A crucial component of the culture medium is the Wnt agonist Rspo, the recently discovered ligand of Lgr5. more...

(Submitter supplied) The intestinal epithelium is continuously regenerated by highly proliferative Lgr5+ intestinal stem cells (ISCs). The existence of a population of quiescent ISCs has been suggested yet its identity and features remain controversial. Here we describe that the expression of the RNA-binding protein Mex3a labels a subpopulation of Lgr5+ cells that divide less frequently and contribute to regenerate all intestinal lineages with slow kinetics. more...

(Submitter supplied) Hippo signalling has been implicated as a key regulator of tissue regeneration. In the intestine, ex vivo organoid cultures model aspects of crypt epithelial regeneration. Therefore in order to uncover the Yap regulated transcriptional programs during crypt regeneration we performed RNA-sequencing of Yap wt and Yap deficient organoids, as well as organoids inducibly expressing Yap.

(Submitter supplied) The weekly turnover of the intestinal epithelium is driven by multipotent, Lgr5+, crypt base columnar cells (CBCs). In response to injury, however, Lgr5+ cells are lost but then re-emerge and are required for successful recovery. How these resurgent Lgr5+ stem cells arise is unclear. We transcriptionally profiled single cells from regenerating intestinal epithelia and identified a unique cell type we term the revival stem cell (rSC). more...

(Submitter supplied) The essential functions of intestinal stem cells (ISCs) are to self-renew and give rise to progenitors that subsequently differentiate to absorptive or secretory cells, thus maintaining homeostasis in the intestinal epithelium. In this study, we analyzed the transcriptomic and epigenetic changes of ISCs with Klf5 deletion to understand the role of KLF5 in ISC identity and functions.

(Submitter supplied) Alcohol increases intestinal permeability to pro-inflammatory microbial products including endotoxin and this is a key step in alcohol-induced organ damage such as alcoholic liver disease. Elevated intestinal permeability is observed even after a period of sobriety. We sought to investigate mechanisms contributing to long-term effects of alcohol on intestinal permeability by testing the hypothesis that alcohol affects intestinal stem cells using ex vivo organoids generated from jejunum and colon from chronic alcohol fed mice.

(Submitter supplied) The intestinal epithelium is the most rapidly self-renewing tissue in adult mammals. We have recently demonstrated the presence of approximately six cycling Lgr5+ stem cells at the bottoms of small intestinal crypts1. We have now established long-term culture conditions under which single crypts undergo multiple crypt fission events, whilst simultanously generating villus-like epithelial domains in which all differentiated cell types are present. more...

(Submitter supplied) Adult stem cells residing within tubular glands of the corpus epithelium are believed to fuel daily tissue renewal, but their identity remains controversial. Lgr5, marks both homeostatic stem cells and “reserve” stem cells in multiple tissues. Here, we report Lgr5 expression in a subpopulation of chief cells in mouse and human corpus glands. Using a new, non-variegated Lgr5-2A-CreERT2 mouse model, we show by cell fate mapping that Lgr5-expressing chief cells do not behave as corpus stem cells under homeostatic conditions, but are recruited to function as stem cells to effect epithelial renewal following injury. more...

(Submitter supplied) The currently accepted intestinal epithelial cell organization model equates crypt base columnar (CBC) cells, marked by high levels of Lgr5 expression, with the intestinal stem cell (ISC). However, recent intestinal regeneration studies have uncovered limitations of the ‘Lgr5-CBC’ model, leading to two major views: one favoring the presence of a quiescent reserve stem cell population, the other calling for differentiated cell plasticity. more...

(Submitter supplied) The identification of Lgr5 as an intestinal stem cell marker has made it possible to isolate and study primary intestinal stem cells. Transcriptional differences between intestinal stem cells can be explored by the use of the Lgr5-eGFP-ires-CreERT2 knock-in mouse. In this mouse model GFP expression is driven from the Lgr5 locus, leading to highest GFP levels in the Lgr5 positive cells. Yet, due to the stability of the GFP protein, it is distributed upon cell division to the daughter cells. more...
