Figure 3.

Representative histology sections. Sections corresponding to the untreated and treated lesions in the same mouse are shown in the first and second row respectively, whereas each column corresponds to a different staining (Caspase 3-1 and 14 days after IRE, H&E, F4/80 and CD3). Image magnification is 40 × for all panels. Extensive apoptosis is evident at 1 day and no more visible at 14 days in treated tumors; a lower number of tumor cells, as well as a higher number of macrophages and T cells, are present at 14 days in treated tumors.
