Figure 2. A) TUNEL staining in fair, intermediate and dark skin 1 d after exposure to 180–200 J/m2 UV; green and red fluroescence represent TUNEL and DNA, respectively. B) TUNEL staining in reconstituted 3-dimensional human skin equivalents containing melanocytes derived from Black, Asian, or White donors and Keratinocytes from the same hispanic donor, 2 d after UVB irradiation; green and red fluroescence represent TUNEL and DNA, respectively. C) p53 phosphorylated at Ser-46 in fair, intermediate and dark skin 1 d after 180–200 J/m2 UV; green and red fluorescence represent TUNEL and p53 phosphorylated at Ser-46, respectively.
