Morphology of the superficial vessels supplying a subcutaneous human glioma xenograft, as assessed by intravital microscopy. Shown is a representative image demonstrating that the tumor is supplied by highly tortuous, disorganized vessels that lack the structural and hierarchical organization seen in the microvascular networks of healthy tissues. The image was acquired at ×40 magnification. For details, see the article by Dickson et al. on page 531.
