CSF1R and neoplasm: For example, tumour‐entrained neutrophils (TENs) with CD11b+ (Ly‐6G)+ inhibited metastatic seeding (Granot et al, 2011), while tumour‐associated macrophages (TAMs), including metastasis‐associated macrophages (MAMs) with CD11b+, F4/80+  and CSF‐1R+, enhanced tumour progression and metastasis (Qian & Pollard, 2010; Qian et al, 2015).
