One of the main goals of stem cell research is to re-grow damaged tissue with fresh tissue that is genetically matched to the patient. This would not only prevent rejection of the implanted tissue but also get around the problem of the chronic shortage of human organs for transplant. In April, a team of British scientists at the Heart Science Centre at Harefield Hospital in Middlesex, UK, led by the world's leading heart surgeon Sir Magdi Yacoub, turned stem cells from bone marrow into functioning heart cells and then used these to make tissue that worked like a heart valve. This marks a significant step towards growing whole replacement hearts from stem cells, an objective that Yacoub said could be achieved in just 10 years.
