Mutagenicity and genotoxicity of e-cigarette liquids in V79 cells. A Colony forming ability of V79 cells after 72 h (ECL; ECL-N; NIC) and 1 h (H2O2), treatments normalised to control (ctrl). B Number of HPRT(-) cells per 1 × 106 seeded V79 cells after 6 days of recovery from treatments. C Number of HPRT(-) cells per 1 × 106 cells normalised to colony forming ability after treatments. A–C Data are presented as mean ± SEM from six independent replicates. D The level of DNA damage in V79 cells determined by single cell gel electrophoresis (Comet assay)—tail DNA (%) of V79 cells after 72 h (ECL; ECL-N; NIC) and 1 h (H2O2) treatments. Data are representative of three independent experiments. E Representative images of tail DNA (comets) of treated V79 cells
