Cell viability of mouse fibroblasts. Effect of different concentrations (0.1 - 100 mg/ml) of freeze-dried myrtle berry homogenates on the cell viability of mouse fibroblasts. Mouse fibroblasts were cultured in Dulbecco’s Modified Eagle Medium (DMEM), and incubated with re-suspended freeze-dried homogenates for 24, 48, and 72 h. The percentage of viable cells was measured through the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. A myrtle homogenate fermented for 48 h at 30°C with Lactobacillus plantarum C2 (Mf) and a myrtle homogenate non-inoculated and chemically acidified, incubated under the same conditions (Mct), were assayed. α-Tocopherol (α-tp, 250, 500, and 100 μM) was used as the positive control. Data are the means of three independent experiments twice analysed.
