Abstract: © 2016 Elsevier B.V. Purpose To study the effects of electroporation on different cell lines. Material The effects of electroporation on human breast cancer (MDA-MB-231), human colon cancer (SW-480 and HCT-116), human fibroblast cell line (MRC-5), primary human aortic smooth muscle cells (hAoSMC) and human umbilical vein endothelial cells (HUVEC) were studied. Real-time technology was used for cell viability monitoring. Acridine orange/ethidium bromide assay was applied for cell death type determination. A numerical model of electroporation has been proposed. Results Electroporation induced inhibition of cell viability on dose (voltage) dependent way. The electroporation treatment 375–437.5 V cm− 1 caused irreversible electroporation of cancer cells and reversible electroporation of healthy cells. The application of lower voltage rating (250 V cm− 1) led to apoptosis as the predominant type of cell death, whereas the use of higher voltage (500 V cm− 1) mainly caused necrosis. Conclusion Electroporation represents a promising method in cancer treatment. Different cancer cell lines had different response to the identical electroporation treatment. Electroporation 375–437.5 V cm− 1 selectively caused permanent damage of cancer cells (SW-480), while healthy cells (MRC-5, hAoSM and HUVEC) recovered after 72 h. The type of cell death is dependent of electroporation conditions. The proposed numerical model is useful for the analysis of phenomena related to electroporation treatment.
