Neurog2 overexpression (Figure 7A, green cells showing the Neurog2-GFP infected GBM cells) led to an efficient neuronal conversion, indicated by immature neuronal marker DCX staining (Figure 7A–7C, quantified in 7B: Neurog2, 92.8% ± 1.2%, DCX+/GFP+, 3 weeks post transplantation, N = 3 mice). Here, DCX is linked to glioblastoma.
