The authors regret In the ‘Results’ section, 3.1. the pictures in Fig. 1. (A) were used by mistake, these pictures were transmission electron microscope images to show the existence of extracellular vesicles, these two pictures were saved in a wrong file by mistake and then used incorrectly, we would like to replace the wrong pictures into right ones. The authors would like to apologise for any inconvenience caused. Declaration about replacement of pictures Recently, when our research group reviewed our work of last year, we found that there was a problem in one of our articles published in Cancer Letters 466(2019)1–12 entitled with “Glioblastoma extracellular vesicles induce the tumour-promoting transformation of neural stem cells”. The pictures in Fig. 1 (A) of this article were used by mistake, these pictures were transmission electron microscope images to show the existence of extracellular vesicles, these two pictures were saved in a wrong file by mistake and then used incorrectly. Now, we would like to take the responsibility to replace the wrong pictures into right ones, and we regret deeply for our mistake and feel so sorry for the subsequent adverse impact. The right ones are dislpayed below. [Figure Presented] © 2020 Elsevier B.V.
