Primitive neuroectodermal tumor of the midbrain in a murine model of retinoblastoma.

abstract：PURPOSE:Vascular endothelial growth factor (VEGF) is required for vascular development and for ischemia-related tumor, iris, and retinal neovascularization. The role of VEGF in inflammatory corneal neovascularization is unknown and was investigated in these studies. METHODS:A rat model was used in which removal of the...
