Figure 3: UVA - Induction of dermal fibroblast alterations within the dermal equivalent after UVA exposure of reconstructed skin. Disappearance of dermal fibroblasts (arrows) 48 hours after UVA exposure (25J/cm²) shown on reconstructed skin section stained by HES (×200)-Visualization of oxidative stress after incorporation of dichlorofluorescin diacetate DCFH-DA probe (green signal)
