CD8A and hepatocellular carcinoma: After QC, we divided 89,655 cells into 45 cell clusters, which were identified into 15 distinct cell types based on known markers (Fig. 1B), including HCC cells, epithelial cells (Ep), endothelial cells (En), fibroblasts (Fib), CD8+ T cells, NKT cells, Naive.T cells, NK cells, B cells, macrophages (Mac), neutrophils (Neu), monocyte-derived dendritic cells (MDDC), plasmacytoid dendritic cell (pDC), and innate lymphoid cells (ILC).
