Figure 8. Irradiation increased neovascularization in the con-tralateral corpus callosum.

Figure 8.

Tumor neovascularization is observed after staining for von-Willebrand factor (vWF) (40× magnification) in baseline, nonirradiated, and irradiated tumors (upper panel). Fluorescein isothiocyanate (FITC)-tagged lectin staining also shows neovascularization in baseline, nonirradiated, and irradiated tumors (middle panel). vWF-positive areas are seen crossing the midline along the corpus callosum in rats receiving radiation (10× magnification) (lower panel). Although irradiated tumors exhibit a relative increase in the number of vessels, analysis of mean microvessel density did not reveal any significant changes in irradiated tumors compared with baseline or nonirradiated tumors.
