Angiogenesis-related growth factors in brain tumors

Numerous growth factors have been implicated in glioma angiogenesis. This chapter focuses on the role of scatter factor/hepatocyte growth factor, fibroblast growth factor, platelet-derived growth factor and transforming growth factor beta. We review the expression pattern of these factors in gliomas, their functional contribution to tumor angiogenesis - also in relation to vascular endothelial growth factor, and the effects resulting from their inhibition or overexpression in gliomas in vivo.
