Why are tumour blood vessels abnormal and why is it important to know?

J A Nagy et al. Br J Cancer. .

Abstract

Tumour blood vessels differ from their normal counterparts for reasons that have received little attention. We report here that they are of at least six distinct types, we describe how each forms, and, looking forward, encourage the targeting of tumour vessel subsets that have lost their vascular endothelial growth factor-A (VEGF-A) dependency and so are likely unresponsive to anti-VEGF-A therapies.

Vascular patterns induced by Ad-VEGF-A164 (A, B) and by MOT, a mouse ovarian tumour (C). (A, B) FA and DV (black arrows) at 27 and 59 days after s.c. injection of 108 PFU of Ad-VEGF-A164. Most angiogenic vessels except for VMs (yellow arrows) have resolved. (C) Mouse ovarian tumour 10 days after s.c. implantation. Black arrows indicate some FA and DV; T, tumour.
