Brain tumour models grown in space could aid glioblastoma treatment

Researchers say glioblastoma organoids grown in space could help advance treatments for the most common malignant primary brain tumour in adults. Glioblastoma is among the deadliest cancers: microscopic 'tentacles' spreading into healthy brain tissue make full surgical removal difficult, and the tumour creates an immunosuppressive environment that helps it evade the immune system and resist therapy.
