Among the cellular components of the perivascular TME, analyzed by ST and mIF imaging, cancer cells dominated the landscape of the omental metastasis in untreated mice and those receiving monotherapy with TCRTAG cells, evidenced by higher levels of keratin 8 (Krt8) gene expression (Fig. 4a) and density of Krt8+ cells (Fig. 4b) with tight concentrations of the tumor cell nuclei (Fig. 4c and d). This evidence concerns the gene KRT8 and cancer.
