scRNA-seq of 81,139 cells from five kidney allograft biopsies reveals all major kidney and immune cell types. (A) Uniform Manifold Approximation and Projection (UMAP) plot of 81,139 cells from five kidney allograft biopsies. All the main kidney cell types are represented, including activated tubular cells, loop of Henle (LOH), proximal tubule (PT), principal cells (PC), intercalated cells (IC), endothelial cells (EC), stromal cells, macrophages, and lymphocytes. (B) Violin plot demonstrating marker genes for major cell types represented in the whole data set and UMAP plot.
