Windpipe transplant is synthetic organ first

Surgeons in Sweden have carried out the world's first synthetic organ transplant. Scientists in London created an artificial windpipe which was then coated in stem cells from the patient.

Crucially, the technique does not need a donor, and there is no risk of the organ being rejected. The surgeons stress a windpipe can also be made within days.

The 36-year-old cancer patient is doing well a month after the operation. The BBC's Fergus Walsh reports.
