Figure Lengend Snippet: ( A ) Graphs depicting main cluster interactors based on incoming and outgoing interaction strengths in the tumor edge (left) and in the tumor core (right). ( B ) Representative immunofluorescent staining (left) and corresponding spatial plots (right) of CD8 + T cells (CD8 + ), monocytes (Mono, CD14 + IBA1 − ), and MoMs (CD14 + IBA1 + ) in the tumor edge and tumor core. Scale bars, 50 μm. ( C ) SpatialScore calculated from immunofluorescent data per patient in tumor edge and tumor core. Error bars denotes means ± SEM. P values, Wilcoxon rank-sum test. ( D ) Heatmap depicting selected ligand-receptor interactions from T cell clusters to THBS1 + monocytes (top) and LR interactions from THBS1 + monocytes to T cell clusters (bottom), enriched in the tumor edge. ( E ) Heatmap depicting selected LR interactions from THBS1 + monocytes to T cell clusters, enriched in the tumor edge. ( F ) Scatter plot shows the correlation between the abundance of SPP1 + macrophages and exhausted CD8 + T (CD8 + Tex) cells in the CRLM microarray dataset GSE159216 ( n = 171). The error band indicates the 95% confidence interval. In (D) and (E), color intensity represents the probability of communication. DAPI, 4′,6-diamidino-2-phenylindole.
Article Snippet: Sections were then incubated with primary antibodies at 4°C overnight followed by incubation with fluorophore-conjugated secondary antibodies (table S11) and nuclear dye 4′,6-diamidino-2-phenylindole (Thermo Fisher Scientific) at room temperature for 2 hours.
