Vascular permeability factor

Vascular permeability factor, also known as vascular endothelial growth factor (VEGF), is a protein that promotes the growth of new blood vessels and increases the permeability of blood vessels. This means it helps blood vessels become more "leaky," allowing fluids, nutrients, and immune cells to pass through more easily into surrounding tissues. VEGF plays a crucial role in wound healing and normal tissue growth, but it can also contribute to pathological conditions like cancer, where it encourages tumors to develop their own blood supply, supporting their growth.
