To elucidate the high-resolution landscapes of tumor-infiltrating immune cells (TIICs) within murine syngeneic tumor models, we performed scRNA-seq on CD45+ immune cells isolated from ten treatment-naïve models, encompassing seven prevalent cancer types: breast mammary carcinoma (4T1, EMT6, MMTV-PyMT), colon carcinoma (CT26.WT, MC38), glioma (GL261), renal adenocarcinoma (Renca), lung carcinoma (LL2), melanoma (B16F10), and pancreatic adenocarcinoma (Pan02) (Figures 1A, D). This evidence concerns the gene PTPRC and central nervous system cancer.
