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

ABSTRACT: 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.

m6A modification segregates the stemness program from proliferation in ISCs [scRNA-seq]

Project description:Purpose: To monitor the different of ISCs and cell fate alteration upon Mettl3 deletion, we use single cell sequencing to examine the sequence information from individual cells with optimized next-generation sequencing (NGS) technologies, providing a single-cell resolution of cellular differences. Methods:Alive intestinal epithelial cells were sorted from WT and Mettl3-KO mice at 4 dpt. 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, 7865 cells (4467 WT and 3398 KO) were analyzed. Conclusions: Mettl3 deletion reduced the expression of stem cell signature genes but unchanged proliferation profile in ISCs. Thus, we conclude that Mettl3 deletion leads to loss of stemness but not proliferation, and enhanced regeneration and apoptosis.

Epithelial cell diversity in small intestine of pigs

Project description:To establish better understanding of specific epithelial cells found across different regions of the small intestine in pigs, we utilized single-cell RNA sequencing (scRNA-seq) to recover and analyze epithelial cells from duodenum, jejunum, and ileum. Cells identified included crypt cells, enterocytes, BEST4 enterocytes, goblet cells, and enteroendocrine (EE) cells. Overall, results provide new information on regional localization and transcriptional profiles of epithelial cells in the pig small intestine.

High resolution single cell transcriptomics reveals heterogeneity of self-renewing hair follicle stem cells

Project description:Purpose: To dissect the transcriptomic profiles and unravel population-specific transcriptional heterogeneity of self renewing hair follicle stem cells in vivo Methods: We performed 10x genomics single-cell RNA sequencing (scRNA-seq) of FACS sorted CD34+/K14-H2BGFP+ hair follicle stem cells from mouse skin at mid-anagen. FACS purified CD34+/K14-H2BGFP+ single-cell suspension was processed for the barcoded single-cell 3′ cDNA libraries generation using Chromium Single Cell 3′ gel bead and library Kit v3. The final libraries were quantified using Agilent Bioanalyzer high sensitivity DNA chip and sequenced using an Illumina NextSeq-500. The raw data files were demultiplexed to generate the sample-specific FASTQ files, which were aligned to the mouse reference genome (mm10-3.0.0) using the 10x Genomics Cell Ranger pipeline (v3.1.0). The raw scRNA-seq data was processed using Cell Ranger from the 10x platform to generate an expression matrix that was further analyzed in R using the Seurat package version 3.1. Only high-quality cells that had between 200 and 5000 genes expressed and had under 10% of the UMIs mapped to mitochondrial genes were retained. Results: We obtained a total of 6736 high quality cells from two datasets for further analysis by Seurat workflow Conclusions: Obtained high quality single cell transcriptomic data to dissect molecular heterogeneity of hair follicle stem cells
