A. Schematic of in vivo experimental timeline. B. Quantitative analysis of chemiluminescent intensity from the cytokine array measurements. (n = 4 per group). C,D. Quantitation of flow cytometric data from 4T1 (C) and EMT6 (D) tumors represented as % of tumor infiltrating TAMs. M2 macrophages are defined as Cd11b+, F4/80+ LY6C−, Arg1+ and Cd206+ populations, and M1 macrophages are defined as Cd11b+, F4/80+, LY6C−, Cd80+, Cd86+ populations (n = 7 per group). E, F. Immunofluorescent staining from 4T1 (E) and EMT6 (F) tumors for Cd206 (green), F4/80 (red), and DAPI (blue). White arrows point to M2 macrophages (F4/80+ Cd206+). Magnification bar is 15μm. G. GSEA Enrichment plots from RNA-seq of bulk 4T1 tumor mass depicting changes in macrophage related signatures. H,I. Pathway analysis of RNA-sequencing data shows top pathways based on number of relevant genes in (H) and top pathways based on significant p-value in (I). *P<0.05
