Opponents of stem cell research might want to reconsider their position if any of their nearest and dearest have ever had heart problems. A team of British scientists has successfully grown a human heart valve from stem cells, an astonishing feat 10 years in the making.
Heart surgeon Sir Magdi Yacoub, who led the team, said doctors could be using artificially grown heart components in transplants within three years.
His researchers at Harefield hospital managed to grow tissue that works in the same way as human heart valves.
Sir Magdi told the Guardian newspaper a whole heart could be produced from stem cells within 10 years.
