We defined 3 lymphocyte subgroups [myeloid cells (marker gene: LYZ), T cells (marker gene: CD3D), and B cells (marker gene: CD79A)], endothelial cells (marker gene: CLDN5), alveolar cells (marker gene: CLDN18), fibroblasts (marker gene: COL1A1), epithelial cells (marker gene: CAPS), and cancer cells (marker gene: EPCAM) (Figure 1C and Supplementary Table 3). This evidence concerns the gene CD3D and cancer.
