Comparison of cytotoxic and mutagenic effects in mouse lymphoma cells treated with CSCs from same cigarette machine smoked under the different conditions. The CSCs of US ‘light’ non-menthol brand cigarettes were produced under ISO conditions (LT) or MDPH conditions (LTMAS), respectively. (A) the microwell version of the MLA; (B) the soft agar version of the MLA; (filled circles) LT; (inverted triangles), LTMAS; solid line, mutagenic effects presented as mutant frequency per million cells; dashed line, cytotoxic effects presented as relative total growth (%).
