When overlaying gene expression of CXCL9, CD3D (t cells) and CD68 (macrophages) (see Supplementary Fig. 17), we see moderate spatial correlation with CXCL9 and CD3D (r = 0.4, p = 3E-29) along the tumor-stromal interface, and weaker correlation with CD68 (r = 0.17, p = 1E-10). This evidence concerns the gene CXCL9 and neoplasm.
