The myeloid cell subsets, including M1 macrophages, M2 macrophages, mDCs, and MDSCs in the tumor, were detected by FCM using a mixture of related membrane cell markers (CD11b, CD45, CD86, CD206, CD11c, and Gr-1) as shown in Figures 3(a) and 3(b). The gene discussed is MRC1; the disease is neoplasm.
