(Top row) Mapping of TSTR cells (in red) on the histology image based on corresponding spatial transcriptomics data generated from the same tissue section. (Rest of the rows) spatial co-mapping of TSTR cells (in red) and hypoxia-related gene expression (in blue, the darker the color, the higher the level of gene expression) in the same regions as shown in the top row. BRCA, breast cancer; CSCC, cutaneous squamous cell carcinoma; GAC, gastric adenocarcinoma; ccRCC, clear cell renal cell carcinoma; LUAD, lung adenocarcinoma.
