MRC1 (CD206) and F13A1 are broadly expressed across tissue-resident macrophage populations, while FCN1 (ficolin-1) shows enriched expression in monocyte populations. Together these markers define the macrophage and monocyte compartment encompassing LAMs, PVMs, inflammatory macrophages, proliferating macrophages, classical monocytes, non-classical monocytes, and CD14⁺S100A8/9⁺ monocytes.
