Scientists are morphing tissue cells into working blood vessels and engineering them to act as artificial pacemakers, according to findings presented at a major medical meeting on Sunday.



The techniques involve manipulating cells from one organ, say a muscle, to form different tissue types, for example a heart cell. Researcher hope the technology when perfected will aid in repairing broken vessels and cells in sick patients. More here.



In one study, researchers took human cells from 11 heart disease patients, manipulated them in a culture and implanted them into animals with broken arteries.
