PDGF-C affects the transvascular flux of BSA.

<p>A: Effective vascular permeability was measured 6 days and 15 days after tumor implantation. The vessels in PDGF-C overexpressing tumors have lower permeability both 6 and 15 days following implantation. Normal brain (NB) vessels are relatively impermeable. B: Delivery of the BSA marker (red) is inhibited by PDGF-C overexpression (Green = CD31).
