PTPRC and neoplasm: To gain unbiased information on not only T cells but also other tumor‐infiltrating immune cells such as macrophages and dendritic cells (DCs), we performed single‐cell RNA sequencing (scRNA‐seq) for enriched CD45+ CD3+ tumor‐infiltrating cells combined with non‐T cells in tumors at a 3:1 ratio (Figure 4A).
