Compared with NE-4C cells, the tumor showed a general tendency of upregulation of a series of genes representing neural stemness (Fig. 2c), genes representing neuronal differentiation (Fig. 2d), and genes representing mesodermal (Acta2, T, Desmin, Kdr) and endodermal tissue (Afp, Foxa2) differentiation (Fig. 2e). The gene discussed is AFP; the disease is neoplasm.
