Comparison of the viabilities of WB-F344 and WB-ras cells with the viability of HaCaT and SK-MEL-28 cells after treatment with 1-min PTM, μsPEFs (1.5 kV/cm) or a combination of both, determined 24 h after exposure.

Significant differences in cell viability are marked for the different treatment methods compared to control (*), for the combined treatments compared to the respective μsPEF-treatment alone (#) and for the two treatment orders (˄). Bars show mean values of three independent experiments performed in triplicates ± standard errors.
