Specifically, myeloid and lymphoid infiltrates, including T and NK cells, were detected in all 3 data sets (antibodies are listed in Supplemental Table 2), and the pervasiveness and intensity of myeloid cell markers, including CD11B and arginase 1, were much higher compared with lymphoid markers in all 3 tumor models (Figure 1 and Supplemental Figure 3, A and B). Here, ARG1 is linked to neoplasm.
