Manchester Scientists rewrite our understanding of how arteries mend

Description

Scientists from The University of Manchester have discovered how the severity of trauma to arterial blood vessels governs how the body repairs itself.

Dr Urmas Roostalu says the discovery could have major implications on how complications from vascular surgeries are prevented and treated.

Their discovery, published in Circulation Research, shows how with minor surgical trauma caused by procedures such as  angiography, stenting, arterial lines and minor surgery, vessels heal by the rapid division of smooth muscle cells – the most important layer in the blood vessel wall, which controls and regulates blood flow.
