Effect of arantho EO on the cellular viability and on morphological changes a Cell viability was evaluated by MTT assays using different concentrations and times of incubation (24, 48 and 72 h) of EO on MDA-MB-231, a breast carcinoma cell line, and MCF-10A, an epithelial breast cell line. b Morphological analysis of MDA-MB-231 breast cancer cells without treatment. c Cells incubated with 0.2 % DMSO. d Cells exposed to paclitaxel (0.25 μg/mL). e-h Cells incubated with EO (53.81 μg/mL) for 3, 6, 12 and 24 h, respectively.
