Cross-species single-cell transcriptomic analysis reveals divergence of cell composition and functions in mammalian ileum epithelium [scRNA-seq_Mouse]

Project description:Purpose: To reveal the differences on epithelial cell composition, functional assignments and pharmacokinetics among mammals intestine, we use single cell sequencing to examine the conserved and divergent features among species, providing a cross-species single-cell transcriptomic atlases of ileal epithelium Methods:Alive ileum epithelial cells were sorted from three adult mice (10 weeks). ScRNA-seq libraries were generated using the Chromium Single Cell 3’ Reagent Ki V3 (10X Genomics). The libraries were sequenced as paired-end with Illumina Novaseq 6000. Raw reads were aligned to the GRCm38/mm10 Mouse genome, and Cell Ranger (v3.1.0) was used to estimate unique molecular identifiers (UMIs). Raw aligned features were loaded and processed using the Seurat package (v4.0.2). Low-quality cells were filtered if they expressed no more than 200 genes or with more than 20% of mitochondrial genes. Results: After cells with low information content and a high fraction of mitochondrial RNAs were excluded, 1060 cells were analyzed. Conclusions: Eight cell types were identified in mouse ileum based on reported markers, including enterocytes, transient-amplifying (TA) cells, goblet cells, goblet progenitor cells, stem cells, Paneth cells, enteroendorcine cells and tuft cells.

ScRNA-seq libraries were generated using the Chromium Single Cell 3’ Reagent Ki V3 (10X Genomics). The libraries were sequenced as paired-end with Illumina Novaseq 6000. Raw reads were aligned to the Rnor_6.0 Rat genome, and Cell Ranger (v3.1.0) was used to estimate unique molecular identifiers (UMIs). Raw aligned features were loaded and processed using the Seurat package (v4.0.2). Low-quality cells were filtered if they expressed no more than 200 genes or with more than 20% of mitochondrial genes. Results: After cells with low information content and a high fraction of mitochondrial RNAs were excluded, 3040 cells were analyzed. Conclusions: Seven cell types were identified in rat ileum based on reported markers, including enterocytes, transient-amplifying (TA) cells, goblet cells, goblet progenitor cells, stem cells, enteroendorcine cells and tuft cells.

Cross-species single-cell transcriptomic analysis reveals divergence of cell composition and functions in mammalian ileum epithelium [scRNA-seq_Macaque]

Project description:Purpose: To reveal the differences on epithelial cell composition, functional assignments and pharmacokinetics among mammals intestine, we use single cell sequencing to examine the conserved and divergent features among species, providing a cross-species single-cell transcriptomic atlases of ileal epithelium Methods:Alive ileum epithelial cells were sorted from two cynomolgus monkeys (14 years old). ScRNA-seq libraries were generated using the Chromium Single Cell 3’ Reagent Ki V3 (10X Genomics). The libraries were sequenced as paired-end with Illumina Novaseq 6000. Raw reads were aligned to the Mmul_10 Macaque genome, and Cell Ranger (v3.1.0) was used to estimate unique molecular identifiers (UMIs). Raw aligned features were loaded and processed using the Seurat package (v4.0.2). Low-quality cells were filtered if they expressed no more than 200 genes or with more than 20% of mitochondrial genes. Results: After cells with low information content and a high fraction of mitochondrial RNAs were excluded, 886 cells were analyzed. Conclusions: Eight cell types were identified in macaque ileum based on reported markers, including enterocytes, transient-amplifying (TA) cells, goblet cells, goblet progenitor cells, stem cells, enteroendorcine cells, CA7+ cells and tuft cells.

Human ileum epithelium LCMD Project

Project description:The small intestinal epithelium mediates vital functions of nutrient absorption and host defense. The spatial organization of the epithelial cells along the crypt-villus axis segregates them into regions of specialized function. However, many of the mechanisms governing intestinal epithelial cell migration and the coordination of interactions with adjacent cells and the extracellular matrix are not fully understood. We have evaluated in vivo gene expression patterns of ileal epithelial cells in healthy human subjects, isolated by laser capture microdissection from either the villus epithelial or crypt cell regions of the small intestinal mucosa. Expression profiles in villus epithelium and Paneth cell lineages were determined by quantitative real-time PCR, DNA microarray, and immunohistochemistry based methods. Relative expression levels of selected epithelial biomarkers were compared between the ileum, jejunum, duodenum, colon, stomach, and esophagus. Previously established biomarkers as well as a novel and distinct set of genes believed to be linked to epithelial cell motility, adhesion, and differentiation were found to be enriched in each of the two corresponding cell populations. Additionally, high baseline expression levels of innate antimicrobials, alpha defensin 5 (HD5) and regenerating islet-derived 3 alpha (Reg3A), were detected exclusively within the small bowel, most notably in the ileum, in comparison to other sites along the gastrointestinal tract. Our findings provide new and important insights regarding the molecular machinery employed by small intestinal epithelial cells to mediate their function and spatial organization in vivo. Keywords: analysis of epithelial cells from crypt or upper villus regions
