Washington, June 4 : Researchers from London have taken a major step in making the use of artificial veins and arteries in coronary bypass grafts a reality.

They have developed this artificial graft tissue by combining man-made materials with human cells to make it elastic and durable and so it can attach to host tissue.

"Obviously this advance could be a medical breakthrough that saves millions of lives around the world but even more tantalizing is the successful fusing of living cells to nonliving substances that actually—heal—by forming a stronger bond to each other and to host tissue once put in use. This might even be called a start toward 'cyborg engineering,'" said Gerald Weissmann, M. D., Editor-in-Chief of The FASEB Journal.
