Arteriogenesis
Arteriogenesis refers to an increase in the diameter of existing arterial vessels.
==Mechanical Stimulation==
Mechanically, arteriogenesis is linked to elevated pressure, which increases radial wall stress, and elevated flow, which increases endothelial surface stress. The vessel increases in diameter until the stress is normalized (Prior ''et al.'', 2004). Arteriogenesis does not occur every time there is an increase in flow, however. Most vessel networks can handle increased flow without increasing diameter because flow is related to vessel diameter by a power of four. Initial experiments demonstrated this phenomenon in that mature vessels are unlikely to respond to increased flow by increasing diameter, but will respond to decreased flow by decreasing diameter (Brownlee & Langille, 1991). Another experiment showed that increasing shear stress caused an immediate increase in vessel expansion followed by a rapid decrease, as well as demonstrating that the mature vessels do indeed respond more favorably to decreased stress (Tuttle ''et al.'', 2001).
