Antenatal Corticosteroids and Postnatal Fluid Restriction Produce Differential Effects on AQP3 Expression, Water Handling, and Barrier Function in Perinatal Rat Epidermis

Figure 5

Representative images of immunoperoxidase localization of AQP3 in 2 μm semithin paraffin sections of skin from embryonic day 18 rat pups exposed to antenatal corticosteroids (ANSs; 𝑛=3, B^′-B^′′′) and from unexposed controls (Control; 𝑛=3, A^′-A^′′′). Anti-AQP3 labels the plasma membrane of epidermal keratinocytes. The AQP3 labeling intensity is higher in ANSs-exposed rat pups than in controls. Bar = 10 μm.
