We identified 14 cell types for the 189,362 cells, including sample-specific tumor cells (further analyzed in the subsequent section), T lymphocytes (i.e., CD8 T cells, CD4 T cells, other T cells, and cycling T cells), natural killer (NK) cells, B lymphocytes, myeloid cells (encompassing monocytes/macrophages, conventional dendritic cells [cDC], plasmacytoid dendritic cells [pDC], and mast cells), and stromal cells (including endothelial cells, fibroblasts, and keratinocytes; Fig. 1B). The gene discussed is CD4; the disease is neoplasm.
