A Patient-Derived Xenograft Model of Glioblastoma

Glioblastoma (GBM) remains the most common malignant primary brain tumor in adults with a median survival of less than ~15 months. Further understanding and therapeutic development rely on the use of clinically relevant models of GBM. Here, we present our patient-derived in vitro and in vivo models that enrich for GBM stem cells (GSCs), a subpopulation of tumor cells with stem cell-like properties that recapitulate the cellular heterogeneity of its parental tumor and resist conventional therapy and seed disease relapse. For complete details on the use and execution of this protocol, please refer to Vora et al. (2020).
