Glioblastoma (GBM) is a highly angiogenic malignancy that is resistant to
standard therapy; neo-formed vessels of this aggressive malignancy are thought to
arise by sprouting of pre-existing brain capillaries. However, the conventional
anti-angiogenic therapy, which seemed promising initially, shows transitory and
incomplete efficacy. The discovery of vasculogenic mimicry (VM) has offered a new
horizon for understanding tumor vascularization. VM is a tumor cell-constituted,
matrix-embedded fluid-conducting meshwork that is independent of endothelial
cells and is positively correlated with poor prognosis. Therefore, a better
understanding of GBM vasculature is needed to optimize anti-angiogenic therapy.
This review focuses on the signaling molecules and cascades involved in VM in
relation to ongoing glioma research, as well as the clinical translational
advances in GBM that have been offered by the development of optimized
anti-angiogenesis treatment modalities.
