文摘

Intratumoral heterogeneity of glioblastoma is captured by clone libraries Pre-existing multitherapy-resistant glioma cells have a mesenchymal character A gradient of therapy resistance is linked to a proneural-mesenchymal axis Therapy resistance is associated with an altered DNA methylation pattern
