• 3. Text Correction

We have also been alerted to an error in affiliation in the text of the paper: In Section 2.1 Cell lines, sentence 2 and 3: In addition, patient-derived cell lines GBM1 and GBM4 [15] were included in this study. Neural progenitor cells (NP1) and normal human astrocytes (NHA) were obtained from Dr Heiko Wurdak (Leeds Institute of Cancer and Pathology). It should be replaced with the following: The patient-derived tumour models GBM1, GBM4, and the adult human brain progenitor line NP1 were a kind gift from H. Wurdak (Stem Cell and Brain Tumour Group, University of Leeds, Leeds, UK) and were used as previously described in [17,18].
