title: Human recombinant bFGF stimulates corneal endothelial wound healing in rabbits.
abstract: We have previously shown that bovine, human placenta extracted and recombinant human basic Fibroblast Growth Factor (bFGF) are effective in enhancing corneal epithelial wound healing in vivo. In the present study, we investigated the effect of rh-bFGF on the regeneration of injured rabbit endothelium. A standardized wound was created by scraping of endothelial cells with a special device within the boundaries of a central epithelial trephine mark of 7 mm in diameter. A single dose of 1.5 micrograms rh-bFGF was injected into the anterior chamber immediately after wounding, while control eyes received the vehicle only (n = 27). Functional recovery and wound closure rates were assessed by means of ultrasonic pachymetry, corneal button wet weight, endothelial vital staining as well as direct computer assisted surface analysis of Janus green stained corneal buttons. Measurements were carried out 1, 2, 4, and 7 days after injury. Morphological evaluation and cell counts at D4 and D7 were also performed. Significant stimulation of endothelial regeneration in rh-bFGF treated eyes, was observed with all methodological approaches. These results demonstrate the effectiveness of rh-bFGF in enhancing experimental corneal endothelial wound healing and advocate for a possible clinical application of this growth factor in order to preserve endothelial cell function or to promote healing of this important monolayer in case of disease or injury.
