Figure 7: Transmission electron micrographs of skin tissues of two experimental groups of mice after 14 days of treatment (A-B, 1 000× and C-D, 2 000×). A: The control group shows the absence of epidermal layers (EL). B: The group treated with Acanthus leucostachyus extracts shows the presence of epidermal layers. C: The control group shows a completely deformed nucleus (N). D: The group treated with Acanthus leucostachyus extracts shows that the nucleus is in regular shape. Scale bar: 2 μm (A-B), 1 μm (C-D).
