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.

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 pigs (6 months 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 Sscrofa11.1 Pig 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, 730 cells were analyzed. Conclusions: Eight cell types were identified in pig 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.

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.

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.

Project description:Animal models are widely used for biomedical studies and drug evaluation. The small intestine plays key roles in nutrient absorption, hormone secretion, microbiota defense and drug absorption and metabolism. Although the intestinal structure of mammals is conserved, the differences on epithelial cell composition, functional assignments and drug absorption among mammals are largely unknown. Here, cross-species analysis of single-cell transcriptomic atlas of the ileum epithelium from mouse, rat, pig, macaque and human reveals the conserved and differential cell types and functions among species, identifies a new CA7+ cell type in pig, macaque and human ileum, uncovers the distinct expression pattern in enterocytes, enteroendocrine cells and Paneth cells, and defines the conserved and species-specific intestinal stem cell signature genes. The examination of drug absorption across species suggests that drug metabolism in mouse ileum is closer to human while drug transport in macaque ileum is more similar to human. Together, our data provide the comprehensive information about cell composition and functional assignments in five species, and offer the valuable guidance for animal model selection and drug testing.
