Figure 4. Relative VEGF gene expression during C. albicans keratitis. Differential gene expression ratios of vascular endothelial growth factors were determined by real-time RT-PCR throughout the first week. Gene expression levels in corneas with posttraumatic C. albicans keratitis were compared to levels in scarified, mock-inoculated control corneas. Horizontal dashed lines indicate 2 fold threshold expression levels.
