Pediatric glioma stem cells: biologic strategies for oncolytic HSV virotherapy.

ABSTRACT: While glioblastoma multiforme (GBM) is the most common adult malignant brain tumor, GBMs in childhood represent less than 10% of pediatric malignant brain tumors and are phenotypically and molecularly distinct from adult GBMs. Similar to adult patients, outcomes for children with high-grade gliomas (HGGs) remain poor. Furthermore, the significant morbidity and mortality yielded by pediatric GBM is compounded by neurotoxicity for the developing brain caused by current therapies. Poor outcomes have been attributed to a subpopulation of chemotherapy and radiotherapy resistant cells, termed "glioma stem cells" (GSCs), "glioma progenitor cells," or "glioma-initiating cells," which have the ability to initiate and maintain the tumor and to repopulate the recurring tumor after conventional therap
