Now, with the quest to build a heart, researchers are tackling the most complex organ yet. The payoff could be huge, both medically and financially, because so many people around the world are afflicted with heart disease. Researchers see a multi-billion-dollar market developing for heart parts that could repair diseased hearts and clogged arteries.
In additional to the artificial nose, Dr. Seifalian is making cardiovascular body parts. He sees a time when scientists would grow the structures needed for artery bypass procedures instead of taking a vein from another part the body. As part of a clinical trial, Dr. Seifalian plans to transplant a bioengineered coronary artery into a person later this year. His employer, University College London, has designated a person to oversee any future commercialization of it and other man-made organs.
