Single-cell and spatial transcriptomics profile of porcine jejunum and ileum containing Peyer's patches

To establish better understanding of cells found in jejunal and ileal Peyer's patches of pigs, we utilized single-cell RNA sequencing scRNA-seq and spatial transcriptomics to recover and analyze cells and spatial regions from sections of jejunum and ileum containing Peyer's patches. Cells identified via single-cell RNA sequencing included B, T/innate lymphoid cell, myeloid, epithelial, and stromal lineage cells. Spatial dots recovered via spatial transcriptomics belonged to regions including villi, crypts, interfollicular/parafollicular zones, follicles, and muscularis. Overall, results provide new information on regional localization and transcriptional profiles of cells in the pig small intestine.
