Vascular endothelial growth factor-D transgenic mice show enhanced blood capillary density, improved postischemic muscle regeneration, and increased susceptibility to tumor formation.

Vascular endothelial growth factor-D (VEGF-D) has angiogenic and lymphangiogenic activity, but its biologic role has remained unclear because knockout mice showed no clear phenotype. Transgenic (TG) mice expressing the mature form of human VEGF-D (hVEGF-D) were produced by lentiviral (LV) transgenesis using the perivitelline injection method. Several viable founders showed a macroscopically normal phenotype and the transgene transmitted through germ line.
