In the Supplementary Information file originally published with this Article, an error was made during the assembly of Figure S1. In this figure, immunostaining was performed to show that serum cultured GBM cells were negative for neural progenitor markers NESTIN and SOX2 (Figure S1B), and also negative for neuronal markers such as NEUROD1 and DCX (Figure S1C). The authors noticed that the representative image showing NESTIN and SOX2 staining on serum cultured cells in Figure S1B was identical to the image showing NEUROD1 and DCX staining on GBM-3 cells in Figure S1C in the initial file. After carefully checking the original data, the authors realized that the image in Figure S1B is correct, whereas the Figure S1C in the initial file was incorrect owing to erroneous assembly.

This error has been corrected in the Supplementary Information that now accompanies the Article.
