Cell proliferation, macrophage infiltration, and ROS production in photoaged skin. a Cell proliferation evaluated by proliferating cell nuclear antigen (PCNA) staining. Scale bars = 50 μm. Macrophage infiltration evaluated by CD68 staining. Scale bars = 100 μm. ROS production evaluated by dihydroethidium staining. Scale bars = 250 μm. b Epidermal proliferate indices. c Dermis proliferate indices. d Statistics for CD68-positive cell counts. e Skin ROS production statistics. *P < 0.05 indicated a significant difference; n.s., no significant difference between groups
