Project description:The goal of this study was to characterize a single-cell clone derived from pig ileum epithelium. Analyses including RNA-seq demonstrated that this clone was derived from an enteric smooth muscle cell. This clone is named PIC7 in the manuscript.
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.
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.
