Figure Legend Snippet: Figure 5. Cytotoxic T cells (CTLs) exhibit close proximity to tumors with a suppressive impact on tumor proliferation (A) Density gradient in the background indicates distance to tumor islands, with brighter yellow representing greater distance from tumor cells. Left panel only has the gradient whereas the middle, zoomed panel additionally depicts yellow masks of the CTLs and the right panel red dots of helper T cells (TH), respectively. (B) Representative images showcasing markers for T cell phenotyping. (C) T cell gating based on the expression of CD3, CD8, CD45RA, CD45RO, and PD1 to analyze the corresponding T cell subpopulations. (D) Representative images showing CD3- and CD8-positive CTLs in tumor parenchyma (TIL-CTLs) with absent CD45RA and CD45RO expression. (E) Distance heatmap depicting proximity and interactions between tumor cells and T and B lymphocyte subtypes, with lower values indicating higher proximity as in Figure 4E. (F) Histogram of Ki67/Ki67+ tumor cell number as a function of distance from RARO CTLs. Data represent three technical replicates. Statistical significance was determined using one-way ANOVA. ***p < 0.001, **p < 0.01. (G) Representative image displaying masks of tumor cells at varying proximities to RARO TIL-CTLs.
