| Extraction protocol |
Cell sorting was performed byFACS Aria II (BD Biosciences). For scRNA-seq (10x) of mouse samples live, CD3-CD19-Ly6G+ I-A/I-E+ cells were sorted from naïve LN, tumor-draining LN, and TRAMPC1-GP tumors. For human scRNA-seq (10x) fresh kidney tumors were used, antigen-presenting cells were sorted as live, CD45+, CD3-, HLADR+
Single cell RNAseq libraries were generated using the Chromium Single Cell 5’1007Library & Gel Bead Kit (10x Genomics) according to the manufacturer’s protocol. Briefly, cells were sorted and captured into the Gel Beads-in-emulsion (GEMs). After reverse transcription, the GEMs were disrupted and the barcoded cDNA was isolated, pooled, and amplified by PCR (13cycles). The amplified cDNA was fragmented, and subjected to end repair and A-tailing followed by a sample index PCR (16 cycles). The purified libraries were sequenced to a depth of 50,000 reads/cell on a 1013HiSeq3000 (Illumina) with 26 cycles for read 1, 8 cycles for index 1 (i7), and 91 cycles for read 2.

| Data processing |
Alignment, filtering, barcode counting, and unique molecular identifier counting were performed using Cell Ranger v3.1. Data were further analyzed using Seurat v.3.074. Briefly, cells with a percentage of mitochondrial genes below 0.05% were included. Cells with more than 4,000 or less than 1,000 detected genes were considered as outliers and excluded from the downstream analyses. Raw unique molecular identifier counts were normalized to unique molecular identifier count per million total counts and log-transformed. Variable genes were selected based on average expression and dispersion. PCA was performed using variable genes. Clusters were identified using the shared nearest neighbor algorithmin Seurat and t-SNE plots were generated based on selected principal component analysis dimensions. Marker genes were identified by the Seurat function FindAllMarkers. Log normalized data are shown in the form of feature plots with the scale in a range of0 (grey) to 2.5~5 (purple). Gene set scoring was performed using the VISION R package v.1.1.0. Briefly, expression of signature genes is weighted based on predicted dropout probability calculated from nearest neighbors, and the normalized expression summed for all genes in the gene set.
