Generation of immunocompetent somatic glioblastoma mouse models through in situ transformation of subventricular zone neural stem cells.

Disease-relevant in vivo tumor models are essential tools for both discovery and translational research. Here, we describe a highly genetically tractable technique for generating immunocompetent somatic glioblastoma (GBM) mouse models using piggyBac transposition and CRISPR-Cas9-mediated gene editing in wild-type mice. We describe steps to deliver plasmids into subventricular zone endogenous neural stem cells by injection and electroporation, leading to the development of adult tumors that closely recapitulate the histopathological, molecular, and cellular features of human GBM. For complete details on the use and execution of this protocol, please refer to Garcia-Diaz et al.1.
