Human tissue model tracks glioblastoma invasion cell by cell

MedicalXpress | Jul 28, 2026

Glioblastoma is a malignant brain tumor and is among the most aggressive cancers in humans. Despite multimodal therapy with surgery, radiation and chemotherapy, there is still no cure. A major reason is the tumor's invasive behavior: Glioblastoma cells migrate far beyond the visible tumor into healthy brain tissue. These infiltrating cells cannot be completely removed and seed tumor recurrence—often within just a few months.
