For each of the common cell types in the OPSCC microenvironment (endothelial cells, fibroblasts, macrophages, T cells, B cells, and myofibroblasts), the corresponding panel shows meta-programs, as defined using the same approach as performed for malignant cells and shown in Fig. 3d. Shown are the relative expression levels of meta-program genes (rows) in all cells of the corresponding cell types (columns). Top panels indicate the patient of origin for all cells.
