CD8A and cancer: The merged cell population was divided into 14 cell clusters; two main cluster masses in six cancer cells (clusters #6, #10, and #12 from HBV-HCC1 and clusters #1, #4, and #7 from HBV-HCC2), four macrophages (clusters #2, #3, #5, and #10), three adenomas (clusters #9, #11, and a few cells from #2), one ALBhigh hepatocyte (#8), one endothelial cell (#13), one fibroblast (#15), and one CD8A+ T-cell (#14) (Figure 5a,b).
