Effect of virgin olive oil (VOO) on human neurotypic SH-SY5Y cell proliferation. SH-SY5Y cells were treated with different dilutions of VOO (a) or VOO with or without β-amyloid1-42 (Aβ) (b) prior to determination of cell proliferation using MTT Assay (a, b). Photographs of the cells at ×100 magnification obtained using Leica DFC300FX CCD camera (c). For the MTT assay, the growth rates were estimated relative to those of the untreated cells (control) and blanks containing only the growth medium, MTT, and SDS were used to correct the absorbances. Results represent the mean ± SD of triplicate determinations. *Statistically significant (P < 0.05) difference between control and treated cells (control vs each sample)
