We have now noticed that the wrong image of NPCs treated with PDGF-BB alone was inadvertently included in Fig. 1B. Also, the western blot images of GSK-3β was inadvertently included in Fig. 4C. The figures are corrected as shown below. The authors declare that these amendments do not change the result or conclusion of the paper, and apologize for this oversight.
