Analyses of the chromatin and transcriptional basis for lateral inhibition in isolated intestinal epithelial cells.

ABSTRACT: We analyzed chromatin modifications, DNaseI-hypersensitive sites, and occupancy of a key secretory-lineage transcription factor, ATOH1. We found that lateral inhibition in the intestine occurs through ATOH1 exerting direct control within a broadly permissive chromatin state that is established in stem cells and is highly similar in specified progenitors of divergent potential. Mapping chromatin modifications (H3K4me2 and H3K27ac), DNaseI hypersensitivity (DHS), and ATOH1 binding sites in isolated intestinal crypt progenitors and mature intestinal villus cells.

Cells differentiate when transcription factors bind accessible cis-regulatory elements to establish specific gene expression programs. In differentiating embryonic stem cells, chromatin at lineage-restricted genes becomes sequentially accessible, probably by means of 'pioneer' transcription factor activity, but tissues may use other strategies in vivo. Lateral inhibition is a pervasive process in which one cell forces a different identity on its neighbours, and it is unclear how chromatin in equ ...[more]

Gene expression in intestinal epithelial crypt and villus cell populations

Project description:We analyzed gene expression profiles in isolated mouse LGR5+ intestinal stem cells, lineage-specific enterocyte and secretory progenitors, and terminally differentiated villus enterocytes. Gene Ontology analyses of cell type-specific transcripts indicated their expected biological functions. We hybridized Affmetrix 430A 2.0 mouse microarrays with processed RNA isolated from purified Lgr5+ intestinal stem cells, secretory (Sec-Pro) and enterocyte (Ent-Pro) crypt progenitors, and mature villus enterocytes (ENT).

Adult stem cells in the small intestine are intrinsically programmed with their location-specific function

Project description:Differentiation and specialisation of epithelial cells in the small intestine is regulated in two ways. First, there is differentiation along the crypt-villus axis of the intestinal stem cells into absorptive enterocytes, Paneth, goblet, tuft, enteroendocrine or M-cells, which is mainly regulated by WNT. Second, there is specialization along the cephalocaudal axis with different absorptive and digestive functions in duodenum, jejunum and ileum that is controlled by several transcription factors such as GATA4. However, so far it is unknown whether location-specific functional properties are intrinsically programmed within stem cells or if continuous signalling from mesenchymal cells is necessary to maintain the location-specific identity of the small intestine. By using the pure epithelial organoid technique, we show that region-specific gene expression profiles are conserved throughout long-term cultures of both mouse and human intestinal stem cells and correlated with differential Gata4 expression. Furthermore, the human organoid culture system demonstrates that Gata4-regulated gene expression is only allowed in absence of WNT signalling. These data show that location-specific function is intrinsically programmed in the adult stem cells of the small intestine and that their differentiation fate is independent of location-specific extracellular signals. In light of the potential future clinical application of small intestine-derived organoids, our data imply that it is important to generate GATA4-positive and GATA4-negative cultures to regenerate all essential functions of the small intestine.

Group 3 innate lymphoid cells amplify YAP1-driven small intestinal repair

Project description:Ror gamma t-deficient mice lack group 3 Innate Lymphoid Cells (ILC3s) and as a result have increased tissue damage and diminished tissue repair in response to insult. To identify repair programs associated with ILC3 presence the transcriptomes of small intestinal stem cells exposed to damage in the presence or absence of ILC3 were compared. Small intestinal damage was induced in Ror gamma t-deficient Lgr5 reporter mice and littermate controls. Small intestinal epithelial stem cells were purified at days 1 and 4 after damage and subjected to RNA sequencing.

RNA-seq of crypt and villus cells from mouse small intestinal epithelium with an intestinal-epithelial specific deletion of LSD1 compared to wild type controls

Project description:To assess the role of LSD1 in mouse small intestinal epithelium, we isolated small intestinal crypts and villus from wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (cKO) (Villin-Cre+; Lsd1f/f) mice. This experiment uses a new Cre strain with 100% deletion efficiency. RNA was directly isolated from intestinal crypt and villus, and this was used for RNAseq. Gene expression analysis of cKO derived crypt and villus provides a spatially restricted outlook on the maturation status of the intestinal epithelium in the villi and the absence of Paneth cells in the crypt.

Distinct processes and transcriptional targets underlie CDX2 requirements in intestinal stem cells and differentiated villus cells

Project description:To define target genes of the intestine-restricted transcription factor (TF) CDX2 in intestinal stem cells, we performed chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-Seq). We used RNA-sequencing to profile gene expression changes during cell differentiation from mouse intestinal stem cells to mature villus cells, as well as genes perturbed in intestinal stem cells upon loss of Cdx2. We find thousands of genes that change in expression during cell differentiation, including known stem cell and mature markers. Upon loss of Cdx2, hundreds of genes are up and down-regulated in intestinal stem cells, some of which are also bound by CDX2 nearby and constitute candidate direct target genes. CDX2 ChIP-Seq analysis of isolated mouse intestinal stem cells. RNA seq analysis of control mouse villus cells, control intestinal stem cells and Cdx2-deleted intestinal stem cells.

RNA-seq of crypt and villus cells from small intestinal epithelium from mice treated with antibiotics with an intestinal-epithelial specific deletion of LSD1 compared to wild type

Project description:To assess the role of LSD1 in mouse small intestinal epithelium, we isolated small intestinal crypts and villus from wild type (WT) (Villin-Cre -; Lsd1f/f) and intestinal-epithelial-specific knock-out (cKO) (Villin-Cre+; Lsd1f/f) mice.

Gene expression analysis of cKO derived crypt and villus provides a spatially restricted outlook on the maturation status of the intestinal epithelium in the villi and the absence of Paneth cells in the crypt. Additionally, these mice were treated with antibiotics to study epithelium intrinsic changes related to LSD1 deletion but independent of the bacterial microbiome.
