Figure 4. The effect of tomato ketchup extracts, lycopene, α-tocopherol and ascorbic acid on chemotaxis (panel A) and the relation between cell migration and IL-8 concentrations (panel B).
Data are presented as mean ± S.E.M. of 3 triplicates. The effect of the pretreatments was significantly lower (P≤0.05) than the control (only the inflammatory challenge). The concentration of IL-8 showed a significant correlation with chemotaxis (R2 = 0.7316; P≤0.05). Mix AOX: the combination of lycopene, α-tocopherol and ascorbic acid; Hydro: hydrophilic tomato ketchup extract; Lipo: lipophilic tomato ketchup extract.
