CD8A and neoplasm: As showed in Fig. 5a, b, stromal cells, composed of endothelial cells and tumor associated fibroblasts (TAFs), were significantly correlated with some of the DEGs (p < 0.05), while no significant correlation between the immune cells (T cells, CD8 T cells, cytotoxic lymphocytes, NK cells, B lineage, monocytic lineage, myeloid dendritic cells, and neutrophils) with DEGs (p > 0.05).
