Description
Tumor-associated neutrophils (TANs) can be conditioned to become “N2” pro-tumorigenic neutrophils in the tumor microenvironment. TANs have been shown to acquire N2 features and promote multiple aspects of tumor growth in mouse models of many cancers, including non-small cell lung cancer. We developed a novel mouse model for lung squamous cell carcinoma (LSCC): Rosa26LSL-Sox2-IRES-GFP;Nkx2-1fl/fl;Lkb1fl/fl (SNL). SNL mice develop tumors with short latency of ~3 months and SNL tumors have high neutrophil infiltration similar to other LSCC mouse models. We employed this novel model and single-cell RNA-sequencing to profile TANs in SNL lung tumors in comparison to peripheral blood neutrophils (PBNs) from tumor-bearing SNL mice. Overall design: Flow cytometry sorted neutrophils (CD45+CD11B+LY6G+) from freshly isolated SNL lung tumors or peripheral blood from tumor-bearing mice were single-cell RNA sequenced with 10X Genomics.
