immunofluorescence and electron microscopy were used to search for common substrate components in prototype rabbit corneal wounds : epithelial scrape wounds , in which the corneal or conjunctival epithelium migrated over the denuded lamina densa of the corneal basement membrane ( cbm ) , and superficial keratectomy , in which the corneal epithelium migrated over a bare stroma without cbm .
