Insulin boost restores muscle growth in elderly Sep 26, 2009
The endothelium controls blood flow by increasing or decreasing the diameter of capillaries (the smallest blood vessels), and regulates the release of oxygen, nutrients, water and other blood-borne cargo through the capillary walls and into muscles and other body tissues. "Having a capillary dilation induced by insulin is important, because it exposes more muscle to the nutrients and hormones and everything flows better and gets stored away better," Volpi said.

Diesel Exhaust Is Linked To Cancer Development Via New Blood Vessel Growth Sep 3, 2009
In fact, the researchers found that three types of blood vessel development occurred in these areas after exposure to the diesel exhaust: angiogenesis, the development of new capillaries; arteriogenesis, the maturation or re-started growth of existing vessels; and vasculogenesis, the formation of new blood vessels. All of these processes are associated with tumor growth, but unprogrammed angiogenesis in particular can wreak havoc in the human body, Sun said. (Science Daily)
