简介：
Overview
This article describes a preclinical orthotopic mouse model for glioblastoma (GBM) established through the intracranial injection of genetically engineered mouse model (GEM) tumor cells. The model effectively replicates key features of human GBM, allowing for the evaluation of therapeutic strategies.
