Fig. 4From: Assessment of cytotoxicity exerted by leaf extracts from plants of the genus Rhododendron towards epidermal keratinocytes and intestine epithelial cellsMorphological changes of mitochondria 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 MitoTracker® Red CMXRos. Cells treated with 0.5 % DMSO were used as controls. Also depicted are cells incubated with extracts from R. hippophaeoides var. hippophaeoides (A), R. xanthostephanum (B), R. hirsutum (C) and R. racemosum (D). Bars represent 20 μmBack to article page
