A, Comparison of gene expression profiles of TANs and Gr1hi MDSCs from 4T1 tumor-bearing mice to naive neutrophils (left, fold-change vs fold-change, 2-fold change). Expression of these probes was further analyzed in fold-change vs fold-change plots comparing TANs from B16 and Her2 tumors to naive neutrophils (right). 170 of the 214 probes passed the CV<0.5 filter. B, Heatmap showing the expression of the 170 probes identified in A across neutrophils. C, Top 20 canonical pathways enriched for TANs and Gr1hi MDSCs compared to naive neutrophils analyzed by Ingenuity Pathway Analysis.
