Protein may guard new blood vessels from leakageA protein, known as angiopoietin-1 or Ang1, was recently found to increase growth of blood vessels now appears to guard the vessels from leakage as well, which can be seen as a potential boon in treating chronic inflammatory diseases and for new therapies that help in growth of healthy blood vessels in damaged heart and limbs.

It was disclosed that the protein may restore the leaky vessels to normal and blocks the effects of substances turning the vessels leaky besides complementing the action of another natural blood vessel growth stimulant known as VEGF (vascular endothelial growth factor).

The new findings, based on studies of blood vessels in the skin of mice, were reported by researchers at UC San Francisco and Regeneron Pharmaceuticals in the December 24 issue of Science.
