Clusters 1, 5, 11, and 17 all appeared to express significant amounts of CD163 (except cluster 11) and MSR1 (encodes CD204) and variable MRC1 (encodes CD206), classic markers of immunosuppressive/tissue reparative/tumor promoting M2 macrophages (Fig. 6A) [4]. This evidence concerns the gene MSR1 and neoplasm.
