Fig. 5From: Assessment of cytotoxicity exerted by leaf extracts from plants of the genus Rhododendron towards epidermal keratinocytes and intestine epithelial cellsEffects of Rhododendron leaf extracts on the F-actin cytoskeleton of IEC6 and HaCaT cells upon incubation with three different concentrations (5, 50, and 500 μg/mL) of leaf extract for 24 h. The intensity of the phalloidin signal in IEC6 (a) and HaCaT cells (b) reflects F-actin presence, which maintains the cellular architecture. Values are given as mean ± standard deviations from three independent experiments, each performed in triplicates. Statistical evaluation was performed by one way ANOVA-analysis; levels of significance are indicated as *for p < 0.05 Back to article page
