Bioprinting builds 3D model of a brain tumour

Patients who are newly diagnosed with high-grade gliomas (GBMs), one of the most aggressive brain tumours, only have a median survival time of around 15 months – reducing to just 5–7 months for recurrent tumours. Glioma stem cells are thought to be at the root of these poor outcomes, so researchers are focusing on therapies that could target these cells. An important first step is to develop realistic models that will enable scientists to study the biology of glioma stem cells and to investigate the resistance of GBMs to chemotherapy.
