Figure 6. The effect of Y-27632 on collagen after superficial keratectomy. The level of collagen type I was unchanged and collagen type II was negative in both vehicle-treated and Y-27632 treated groups. Collagen type III signal, which was seen in the subepithelial layer in the center of vehicle-treated corneas, was more diffuse in Y-27632 treated corneas. Scale bar: 100 μm.
