Analysis of In Vitro Cyto- and Genotoxicity of Barbatimão Extract on Human Keratinocytes and Fibroblasts

Figure 5

Modulation of oxidative markers on three different cell culture days of keratinocytes and fibroblasts exposed to two different hydroalcoholic barbatimão extracts to evaluate potential chronic genotoxicity of this extract on cells. (a) Reactive oxygen species (ROS) levels; (b) 8-OHdG levels. Data were compared by one-way analysis of variance (ANOVA) followed by a Tukey post hoc test. In each marker tested here, statistical differences at p ≤ 0.05 among 24 h cell cultures treatments were identified by different letters (A, B, C).
