Fig. 6From: Assessment of cytotoxicity exerted by leaf extracts from plants of the genus Rhododendron towards epidermal keratinocytes and intestine epithelial cellsMorphological changes of F-actin structures in IEC6 and HaCaT cells after 24 h exposure to three different concentrations (5, 50 and 500 μg/mL) of Rhododendron leaf extracts. Confocal fluorescence images of IEC6 (a) and HaCaT cells (b) labeled with phalloidin (green) and Draq5™ (blue). Cells treated with 0.5 % DMSO served as controls for cells treated with leaf extracts of R. hippophaeoides var. hippophaeoides (A), R. xanthostephanum (B), R. hirsutum (C) and R. racemosum (D). Bars represent 20 μmBack to article page
