Cell landscapes and differential nutrient absorption preferences of porcine intestines based on single-cell transcriptome profiles. A The Seurat algorithm and t-SNE plot were used to visualize the cell subtypes of all 23,133 intestinal cells. B Expression heatmaps of the top 5 cell type-specific genes in various intestinal epithelial cells. C KEGG analysis of porcine enterocyte-enriched genes at the organismal systems level. D–K Expression patterns of specific genes involved in nutrient absorption and transport in different intestine segments, mainly including lipids (D), short-chain fatty acid (E), sugar (F), amino acids (G), nucleotide or nucleotide sugar (H), vitamin (I), metal ion (J), and water (K). Each dot represented a gene, of which the color saturation indicated the average expression level in an intestine segment, and the size indicated the percentage of cells expressing the gene
