PTPRC and melanoma: 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).
