(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...

(Submitter supplied) The identification of Lgr5 as an intestinal stem cell marker has made it possible to isolate and study primary intestinal stem cells. Applying quantitative mass spectrometry as well as transcriptomic analysis, we profiled the protein and gene changes between FACS-sorted Lgr5+ve stem cells and their immediate undifferentiated daughter cells. The overall comparison of mRNA and protein levels revealed a high level of correlation, implying that the initial control of intestinal stem cell biology occurs largely at the mRNA level. 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) AP4 is frequently expressed in primary CRCs. However, the in vivo relevance of AP4 for development of intestinal tumor formation has not been analyzed by genetic approaches. ApcMin/+ mice with deletion of AP4 were generated and analyzed. The mRNA expression profiles of intestinal adenomas with and without functional AP4 were compared.

(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.

RSPO2 gene has been identified by our group (İstanbul, Turkey, 2014) as responsible gene for Tetra-Amelia with lung aplasia phenotype. To find causative pathogenic variations, sanger sequencing of fetal DNA was performed and did not reveal any variations. more...

(Submitter supplied) Homeostasis of self-renewing small intestinal crypts results from neutral competition between Lgr5 stem cells, small cycling cells located at crypt bottoms1, 2. Lgr5 stem cells are interspersed between terminally differentiated Paneth cells, that are known to produce bactericidal products such as lysozyme and cryptdins/defensins3. Single Lgr5-expressing stem cells can be cultured to form long-lived, self-organizing crypt-villus organoids in the absence of non-epithelial niche cells4. more...

(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 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) At the base of the intestinal crypt, long-lived Lgr5+ stem cells are intercalated by Paneth cells that provide essential niche signals for stem-cell maintenance. This unique epithelial anatomy makes the intestinal crypt one of the most accessible models for the study of adult stem cell biology. The glycosylation patterns of this compartment are poorly characterized and the impact of glycans on stem cell differentiation remains largely unexplored. more...

(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...
