(Submitter supplied) To follow the changes in the transcriptional programs accompanying the specification of the adult ISCs we sequenced whole transcriptomes of embryonic intestinal epithelium progenitors (at E11.5 and E12.5) and adult ISCs. EpCAM positive embryonic gut epithelium was isolated from dissected small intestines using fluorescence activated cell sorting (FACS). Adult ISCs were purified on the basis of GFP fluorescence from crypts of Lgr5GFP-Cre-ERT mice (Barker et al. more...

(Submitter supplied) Intestinal stem cells are required for proliferation, differentiation, and regeneration of the intestinal epithelium. Krüppel-like factor 5 regulates intestinal stem cells in both physiologic and pathological conditions and may be a treatment target in certain diseases of the intestine.

(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) The effort to better understand intestinal stem cell (ISC) identity and regulation remains a challenge. We have been studying the RNA-binding protein MEX3A as a putative ISC marker. In that context, we have generated the first Mex3a knockout (KO) mouse model and show MEX3A is crucial for maintenance of the Lgr5+ ISC pool. As part of a phenotypic characterization pipeline, we have performed transcriptomic profiling (RNA-sequencing) of isolated Mex3a KO small intestinal crypts and compared it against small intestinal crypts isolated from age-matched wild-type controls.

(Submitter supplied) The Lgr5 receptor is a marker of intestinal stem cells (ISCs) that regulates Wnt/b-catenin signaling. In this study, phenotype analysis of knockin/knockout Lgr5-eGFP-IRES-Cre and Lgr5-DTReGFP embryos revealed that Lgr5 deficiency during Wnt-mediated cytodifferentiation results in amplification of ISCs and early differentiation into Paneth cells, which can be counteracted by in utero treatment with the Wnt inhibitor LGK974. 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 molecular mechanisms controlling stem cell renewal and lineage commitment are still poorly understood due to lack of reliable markers. In the adult small intestine, an example of high rate self-renewing tissue, four different epithelial cell lineages (enterocytes, Goblet, enteroendocrine and Paneth cells) are generated from a pool of stem cells localised at the bottom of the crypts of Lieberkühn. more...

(Submitter supplied) The intestinal epithelium is continuously renewed by a pool of intestinal stem cells expressing Lgr5. We show that deletion of the key autophagy gene Atg7 affects the survival of Lgr5+ intestinal stem cells. Mechanistically, this involves defective DNA repair, oxidative stress, and altered interactions with the microbiota. This study highlights the importance of autophagy in maintaining the integrity of intestinal stem cells.

(Submitter supplied) The identification of Lgr5 as an intestinal stem cell marker has made it possible to isolate and study primary stem cells from small intestine. Using the cell cycle specific expression og the mKi67 gene, we generated a novel Ki67-RFP knock-in allele which identifies dividing cells. Using Lgr5-GFP;Ki67-RFP mice, we isolated CBCs with distinct Wnt signaling levels and cell cycle features, and analyzed their global gene expression pattern using microarrays. more...

To determine transcriptional changes upon loss of Tcf7l1, we have isolated EpCAM-positive epithelial cells from mouse embryos using fluorescence activated cell sorting (FACS) and performed RNA-sequencing analysis.

(Submitter supplied) Immortal spheroids were generated from fetal mouse intestine using the culture system developed to culture organoids from adult intestinal epithelium. Spheroids are made of a monostratified polarized epithelium displaying a poorly differentiated intestinal phenotype. The proportion of spheroids generated from intestinal explants progressively decreases from fetal to postnatal period, with a corresponding increase in production of organoids. more...

(Submitter supplied) Aim: The mammalian gut is the largest endocrine organ. Dozens of hormones secreted by enteroendocrine cells regulate a variety of physiological functions of the gut but also of the pancreas and brain. Here, we examined the role of the helix-loop-helix transcription factor ID2 during the differentiation of intestinal stem cells along the enteroendocrine lineage. Methods: To assess the functions of ID2 in the adult mouse small intestine, we used single-cell RNA sequencing, genetically modified mice, and organoid assays. more...

(Submitter supplied) Arid1a, a subunit of the SWI/SNF chromatin remodeling complex, have been reported in multiple human cancers, however, its functional role in intestinal homeostasis remains unclear. To investigate the role of Arid1a in murine intestine, we have employed ChIP experiments in intestinal spheroid cells generated from crypt cells of wild type mice. ChIP assay revealed that Arid1a binds directly to the Sox9 promoter to support its expression.

(Submitter supplied) To define differences in chormatin accessibility and histome modifications in intestinal stem and epithelial cells, we performed ATAC-seq and ChIP-seq. We used RNA-sequencing to profile gene expression changes during intestinal stem cell differentiation into different cell types. We find that gene expression is correlated with the chromatin accessibility and reveals differences between intestinal stem cells types.

(Submitter supplied) A dozen of cells expressing various marker genes was defined as adult gastric epithelial stem cells. Do these cells represent different cell types or they are just the same cell with cycling expression of different marker genes? The origin of the adult stem cells could answer this question. Yet, the identity of the embryonic gastric progenitors was not known. We performed single cell RNA-sequencing to characterize cellular composition of the embryonic stomach at the time of initiation of cytodifferentiation. more...
