Abstract:
Gliomas are heterogeneous tumours derived from glial cells and remain the deadliest form of brain cancer. Although the glioma stem cell sits at the apex of the cellular hierarchy, how it produces the vast cellular constituency associated with frank glioma remains poorly defined. We explore glioma tumorigenesis through the lens of glial development, starting with the neurogenic-gliogenic switch and progressing through oligodendrocyte and astrocyte differentiation. Beginning with the factors that influence normal glial linage progression and diversity, a pattern emerges that has useful parallels in the development of glioma and may ultimately provide targetable pathways for much-needed new therapeutics.
