Corneal Neovascularization after Excimer Keratectomy Wounds in Matrilysin-Deficient Mice
Matrilysin, matrix metalloproteinase (MMP)-7, is upregulated in the corneal epithelium during wound healing after excimer keratectomy wounds. The purpose of this study was to determine the role of matrilysin in maintaining corneal avascularity during wound healing. Matrilysin-deficient mice (n = 17)...

description | Matrilysin, matrix metalloproteinase (MMP)-7, is upregulated in the corneal epithelium during wound healing after excimer keratectomy wounds. The purpose of this study was to determine the role of matrilysin in maintaining corneal avascularity during wound healing.
Matrilysin-deficient mice (n = 17) and their age-matched wild-type littermates (n = 18) were treated with 193 nm argon-fluoride excimer keratectomy (experiment I). The percentage of corneal surface occupied by neovascularization was measured with a computer image-analysis program adjusted for parallax. In another experiment (experiment II), epithelial closure was monitored with slit lamp biomicroscopy and fluorescein staining, and corneal neovascularization was confirmed by india ink perfusion, electron microscopy, and immunolocalization of CD31 and type IV collagen. Corneal micropocket assays were performed to compare the area of corneal neovascularization in matrilysin-deficient mice and wild-type littermates (experiment III). To determine whether the differences in corneal neovascularization were related to differences in angiogenic factors, the levels of basic fibroblast growth factor (bFGF) were compared with those of vascular endothelial growth factor (VEGF) in matrilysin-deficient and wild-type mouse corneas (experiment IV).
The percentages of the corneal surface occupied by neovascularization after excimer laser keratectomy in the matrilysin-deficient mice measured 21.3% +/- 5.2% and 18.7% +/- 5.8% at days 3 and 7, respectively, compared with 5.3% +/- 2.4% and 5.5% +/- 3.4% in the wild-type littermates at days 3 (P < 0.01) and 7, respectively (P < 0.05; experiment I). No significant differences in the rates of epithelial closure of corneal wounds were observed between matrilysin-deficient and wild-type mice after wounding. Corneal neovascularization in the matrilysin-deficient mice was confirmed by india ink present in the corneal stromal blood vessels (extending from the limbus to the wound), immunohistochemical staining, and electron microscopy. Gram, Giemsa, calcofluor white, and acridine orange stains and electron microscopy showed no evidence of corneal infection (experiment II). The area of corneal neovascularization in matrilysin-deficient mice was not significantly different from that of wild-type littermates after implantation of bFGF pellets (0.91 +/- 0.55 mm(2) and 0.77 +/- 0.34 mm(2), respectively; experiment III).
