Human GBM cell lines U251 and A172 were also induced into U251-GSC and A172-GSC, and we detected NEAT1 expression in GL261/GL261-GSC, U251/U251-GSC, and A172/A172-GSC exosomes and found an upregulated expression in all GSC cell lines (Figure 6a, Figure S3). This evidence concerns the gene NEAT1 and glioblastoma.
