Fig 4. Microscopic view of collagen staining of rat hearts.

Fig 4

The collagen staining demonstrates the presence of extended scar tissue in the myocardium that has been treated by IRE. The control slide (left figure) lacks bluish coloring because of lack of scar. In the right figure, the bluish coloring demonstrates well the typical scaring caused by IRE as was observed in our study.
