CD11b+ myeloid cells constituted, on average, >50% of CD45+ tumor-infiltrating cells, of which, 5 main populations were identified (I-V) based on expression of MHC-II, Ly6C, Ly6G and CD11c (Fig. 4a); population I phenotypically resembles neutrophil or gMDSC; populations II/III and IV/V encompasses inflammatory monocytes/mMDSC and TAMs, respectively. The gene discussed is ITGAM; the disease is neoplasm.
