Effects of Citrus bergamia extract (CBE) on mesenchymal stem cells viability, determined using the 3-(4,5-dimethyl-2 thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, after 48 hours of treatment with 1, 10, 50, or 100 μg/mL of CBE. The values of optical density measured at λ = 550 nm are reported as percentage with respect to the optical density registered for untreated control (Control), the latter considered as 100% of cell viability. The values are mean ± SD of three experiments performed in triplicate.
