The hVEGFA-TG mouse is a transgenic model generated by Cyagen. In this model, the expression of human VEGFA CDS is driven by the bovine rhodopsin promoter, allowing for specific overexpression of the human VEGFA gene in the retina without affecting the expression of the endogenous VEGFA gene. This model exhibits clear retinal and choroidal vascular lesions while maintaining complete eye structure and can naturally develop diseases. Anti-VEGF drugs such as Aflibercept have been evaluated for efficacy in this mouse model, demonstrating that Aflibercept can target and suppress VEGF expression, thereby alleviating retinal vascular lesions. As such, this model is well-suited for drug evaluation and mechanism research related to neovascular ophthalmic diseases.
