For patients with glioma, the most common primary brain tumor, new findings may explain why current therapies fail to eradicate the cancer. A UCSF-led team of scientists has identified for the first time that progenitor rather than neural stem cells underly a type of glioma called oligodendroglioma. This distinction explains why oligodendroglioma is more responsive to therapy than other brain tumors such as glioblastoma multiforme. The finding is significant, the researchers say, because it gives cancer doctors and researchers new cellular pathways to target in developing therapies...
