A novel neural stem cell-derived immunocompetent mouse model of glioblastoma for preclinical studies

2020

AbstractGlioblastomas are the most lethal tumors affecting the central nervous system in adults. Simple and inexpensive syngeneicin vivomodels that closely mirror human glioblastoma, including interactions between tumor and immune cells, are urgently needed for deciphering glioma biology and developing more effective treatments. Here, we generated glioblastoma cell lines by repeatedin-vivopassaging of cells isolated from a neural stem cell-specific Pten/p53 double-knockout genetic mouse brain tumor model. Transcriptome and genome analyses of the cell lines revealed molecular heterogeneity comparable to that observed in human glioblastoma. Upon orthotopic transplantation into syngeneic hosts…
