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

Figure 4

Representative light microscopic observation and scanned images by TScan with various treatments: All representative images were taken both immediately (0 h) and 24 h after scratching with or without SM treatment. Each of scanned images by TScan is shown underneath its corresponding microscopic picture. The AIVP concentrations used are displayed on the left while the treatments for each picture column are shown at the top. The scale bar on the top left panel shows 100 μm. a: immediately after scratching (0 h); b: 24 h after scratching; c: 24 h after scratching with 1/500k AIVP; d: 24 h after scratching with 1/50,000 AIVP; e: 24 h after scratching with 1/5,000 AIVP; as: immediately after scratching (0 h) with SM; bs: 24 h after scratching with SM; cs: 24 h after scratching with SM + 1/500,000 AIVP; ds: 24 h after scratching with SM + 1/50,000 AIVP; es: 24 h after scratching with SM + 1/5,000 AIVP. The scale bar on the top left panel shows about 0.5 μm.
