While there are differences in the flow cytometric phenotypic markers of relevant tumor-associated cell types between humans and mice, and even within murine studies, in the current work we defined MDSCs as CD11b+Ly6ChighLy6Glow cells, tumor-associated neutrophils (TAN) as CD11b+ Ly6CintermediateLy6Ghigh cells, and tumor-associated macrophages (TAM) as CD11b+Ly6ClowLy6Glow cells. The gene discussed is ITGAM; the disease is neoplasm.
