In the version of this article initially published, the x-axis labels in Fig. 8f–h should have read “Days after surgery” and the first sentence of the Methods section should have read “The human glioma cell line U87 was derived from the American Type Culture Collection. The murine glioma cell line GL261 was gifted by Z. Wang (Beijing Institute of Transfusion Medicine, Beijing, China). The cell lines were verified through STR testing (Beijing Microread Genetics Co., Ltd., Beijing, China).” The errors have been corrected in the HTML and PDF versions of the article.
