S100A9 and neoplasm: For myeloid cells, we classified monocytes into classical (CD14+FCN1+S100A8+S100A9+) and non-classical (CD16+LST1+LILRB2+) monocytes24; macrophages into M1, M2 and tumor-associated macrophages (TAMs); and cDCs into cDC type 1 (cDC1), type 2 (cDC2) and a mature and migratory subtype (mregDC; Fig. 2A, Supplementary Fig. 3C).
