Patient-Derived Orthotopic Xenografts and Cell Lines from Pediatric High-Grade Glioma Recapitulate Heterogeneity of Histopathology, Molecular Signatures and Drug Response

We established 21 patient-derived pHGG orthotopic xenograft (PDOX) models and 8 matched cell lines from diverse pHGG subgroups. Models recapitulated histopathology, DNA methylation signatures, mutations and gene expression patterns of the patient tumors from which they were derived, and included rare subgroups not well-represented by existing models. We also included 6 DIPG cell lines generously shared by Dr. Michelle Monje (Stanford University). An online interactive data portal is available to explore associated detailed molecular characterization and HTS chemical sensitivity data. Bisulphite converted DNA from these samples were hybridised to the Illumina Infinium MethylationEPIC or HumanMethylation450 BeadChip
