Figure 6. Olomoucine treatment decreased localization of MMP-2 protein at the wound edge. A: MMP-2 immunofluorescence is elevated at the wound edge in untreated control corneas. B: The immunostaining of MMP-2 at the wound edge (arrow) is reduced in olomoucine-treated corneas. C: Whole mounted corneas without primary antibody showed no immunofluorescence. D: Paraffin sections of wounded control corneas showed MMP-2 immunofluorescence in all layers of the cornea at wound edge (arrow) and in basal epithelial cells distal to the wound (arrowhead). E: The paraffin section of olomoucine-treated cornea showed reduced immunofluorescence of MMP-2 at the wound edge (arrow). MMP-2 immunofluorescence persisted in the basal layers of epithelium (arrowhead). F: No immunostaining was detected in the paraffin section of the cornea when primary MMP-2 antibody was omitted. Scale bar=100 μM.
