Doctors in Sweden have replaced a vital blocked blood vessel in a 10-year-old girl using the first vein grown in a lab from a patient's own stem cells.


The successful transplant operation, reported online in The Lancet medical journal on Thursday, marks a further advance in the search for ways to make new body parts.


It could open the door to stem cell-based grafts for heart bypass and dialysis patients who lack suitable blood vessels for replacement surgery, and the Swedish team said it is now working with an undisclosed company to commercialize the process.
