OBJECTIVE: To investigate the effect of METH1 gene transfection on fibroblast proliferation and I, III collagen synthesis in rabbit ear scar. METHODS: The hypertrophic scar model on the rabbit ears was reproduced. 10 days after epithelization, Ad-METH1 was injected into the scar tissue. 30 days later, the effect of METH1 gene transfection on the angiogenesis, fibroblast proliferation and the ratio of collagen I/III in the scar tissue was detected by microcirculation microscope, AgNOR particle count and collagen dyeing. RESULTS: 30 days after injection of Ad-METH1, angiogenesis, fibroblast proliferation and the ratio of collagen I/III in the scar tissue were obviously suppressed. CONCLUSION: Early application of Ad-METH1 after epithelization can markedly inhibit the formation of the hypertrophic scar.
