Glioblastoma accounts almost 50% of all brain cancers, being the most common and lethal brain tumor in adults. Despite the current standard gold treatment based on surgery, chemotherapy, and radiotherapy, other treatment strategies are needed. Different in vitro models are currently used, including commercial cell lines, patient-derived cell lines, organoids, as well as in vivo models, being orthotopic xenografts the most used ones. In this chapter, we describe a standard protocol for the intracranial inoculation of glioblastoma cells in immunodeficient mice, and how to follow up the tumor progression and analyze the data.
Keywords: Glioblastoma; In vivo; Intracranial injection; Orthotopic mouse model.
