Illustration of FD leakage from blood vessels surrounding the tumor and their constriction after EP and ECT.

<p>Images were acquired at 20×magnification. Control – mice without treatment, Bleomycin – mice treated with bleomycin only, EP – mice treated with EP, ECT – mice treated with ECT. (<b>A</b>) Illustration of FD leakage from blood vessels surrounding the tumor, when FD was injected <i>i.o.</i> before the therapy. Arrows indicate the position of the tumor. Scale bar is 2 mm. (<b>B</b>) Illustration of the constriction of blood vessels surrounding the tumor visualized by FD. The enlarged sections of images were taken at 20×magnification. Scale bar is 500 µm.
