We identified cell types in these datasets, including tumor/epithelial cells, stroma, endothelial cells, myeloid, CD4 and CD8 T cells, B cells, and Tregs based on their representative markers (Methods, available as supplementary data at Bioinformatics Advances online) with lineage marker expression supporting our final cell type predictions (Fig. 1B, Fig. 2A, available as supplementary data at Bioinformatics Advances online). The gene discussed is CD8A; the disease is neoplasm.
