Nitric Oxide Synthase Gene Transfer Overcomes the Inhibition of Wound Healing by Sulfur Mustard in a Human Keratinocyte In Vitro Model

Figure 6

The effect of iNOS gene transfer on iNOS expression with or without SM treatment by fluorescence microscopy: The pictures are representative of five independent experiments. Red (TRITC), green (GFP), and blue (DAPI) colors represent iNOS expression, AIVP transfection, and the nucleus, respectively. The composite (merging the three colors) is shown in the fourth column for each group (±SM). The color yellow indicates that the iNOS expression was due to transfection with AIVP. The scale bar on the top left panel shows about 0.5 μm.
