CCL18+M1, CXCL9+M2, and TIMP1+M3 were enriched in tumor tissues and were regarded as TAMs, whereas SELENOP+M4, MMP7+M5, CHIT1+M6, and PPARG+M7 were enriched in normal tissues and considered as resident tissue macrophages (RTMs) (Supplementary Figure 7A). The gene discussed is SELENOP; the disease is neoplasm.
