Electroporation with 1000 V, 100 microseconds, 1 Hz, 297 pulses.

Applied parameters are given in Table 1. The left electrode is always the anode, while the cathode is on the right side. (A) Magnified H&E and (B) Mason trichromatic stained tissues, focusing on the region between the electrodes. (C) Control. (D) Interface between affected and normal area. (E) The core of the treated region on the left hand side (x10). (F) Magnification (x20) from the core on the left hand side. (G) Left hand side electrode core near a dehydrated region (x10). (H) The left hand side lesion near a large blood vessel. Rectangles and black arrows show the site from which the magnified sample was taken. Scale bars and magnification are given in the figures.
