Submitted June 5, 2003 Accepted September 16, 2003 Tracking angiogenesis induced by skin wounding and contact hypersensitivity using a Vegfr2-luciferase transgenic mouse Ning Zhang*, Zuxu Fang, Pamela R Contag, Anthony F Purchio, and David B West Xenogen Corp., Alameda, CA, USA * Corresponding author; email: ning.zhang{at}xenogen.com. The VEGFR2 gene is transcriptionally regulated during angiogenesis. The ability to monitor and quantify VEGFR2 expression in vivo may facilitate a better understanding of the role of VEGFR2 in different states. Here we describe a transgenic mouse, Vegfr2-luc, in which a luciferase reporter is under control of the murine VEGFR2 promoter. In adult mice, luciferase activity was highest in lung and uterus, intermediate in heart, skin and kidney, and lower in other tissues. Luciferase expression in these tissues correlated with endogenous VEGFR2 mRNA expression. In a cutaneous wound-healing model, Vegfr2-luc expression was induced in the wound tissue. Histological and immunohistochemical studies showed significant macrophage infiltration into the wound and induction of Vegfr2-luc expression in both endothelial and stromal cells. Dexamethasone significantly suppressed both Vegfr2-luc expression and macrophage infiltration into the wound, resulting in delayed healing and impaired angiogenesis. In a skin hypersensitivity reaction produced by treatment with oxazolone, Vegfr2-luc expression was induced in the ear. Treatment by dexamethasone markedly suppressed Vegfr2-luc expression and leukocyte infiltration in the ear, and was correlated with reduced dermal edema and epidermal hyperplasia. The Vegfr2-luc model will be valuable in monitoring the ability of drugs to affect angiogenesis in vivo. CiteULike    Connotea    Del.icio.us    Digg    Reddit    Technorati    What's this?
