Vascular endothelial growth factor (VEGF), also known as vascular permeability factor (VPF), is a highly specific vascular endothelial cell growth-promoting factor, which can promote the increase of vascular permeability, the degeneration of extracellular matrix, the migration of vascular endothelial cells, the proliferation and formation of blood vessels. VEGF has also been confirmed to have a chemotactic effect on monocytes and osteoblasts.
The Recombinant Human Vascular Endothelial Growth Factor (OsrhVEGF) was expressed in the rice endosperm platform, which has been demonstrated that has the same physical and chemical with the native VEGF.
