Researchers grown arteries inside patient's body.

Scientists in Brisbane, Australia have developed a technique for growing arteries inside a patient's body that could help the tens of thousands of people undergoing coronary artery bypass surgery each year.

The technique involves inserting a tube into the body for several weeks, allowing native tissue to grow around it before the tube is removed. Researcher Robert McGinley, PhD from the University of Queensland said the technique has been used successfully in animals and that human trials are about a year away.

"Discovering this novel, autologous transplantation method, where there is no rejection...makes this a very significant step forward for all vascular biology research," McGinley said.
