MRC1 (CD206) and F13A1 are general macrophage markers broadly expressed across tissue-resident macrophage populations. LYVE1, SELENOP (selenoprotein P), and C1QA show enriched expression in perivascular macrophages specifically, with LYVE1 marking macrophages associated with the perivascular niche. Together these markers identify perivascular macrophages (PVMs) and distinguish them from other macrophage subpopulations including LAMs.
