The cells in the GBM samples were divided into 7 categories, three malignant cell (OLIG1 + malignant, n = 11637; VEGFA + malignant, n = 6446; CENPF + malignant, n = 5363), microglia (n = 3219), fibroblasts (n = 1020), endothelial cells (n = 919), and oligodendrocytes (n = 735) (Fig. 8C). The gene discussed is VEGFA; the disease is glioblastoma.
