摘要Diffuse midline glioma (DMG) is a highly aggressive pediatric brain tumor that is difficult to treat because the blood-brain-tumor barrier (BBTB) prevents most drugs from reaching the tumor. A major obstacle for understanding this tumor-vascular niche is the lack of a perfusable vascular model of DMG. To address this, we have established an in vitro model of the DMG-BBTB, comprised of patient-deri...查看完整摘要
