Latest Technology - Scientists make custom-made body parts using stem cells

At London's Royal Free hospital, scientists are growing noses, ears and blood vessels in the laboratory in a bold attempt to make body parts using stem cells.
It is among several labs around the world, including in the U.S., that are working on the futuristic idea of growing custom-made organs in the lab.
Only a handful of patients have received the British lab-made organs so far - including tear ducts, blood vessels and windpipes.

But researchers hope they will soon be able to transplant more types of body parts into patients, including what would be the world's first nose made partly from stem cells.
'It's like making a cake,' said Professor Alexander Seifalian at University College London, the scientist leading the effort. 'We just use a different kind of oven.'
Last year, he and his team made a nose for a British man who lost his to cancer. Scientists added a salt and sugar solution to the mould of the nose to mimic the somewhat sponge-like texture of the real thing.
Stem cells were taken from the patient's fat and grown in the lab for two weeks before being used to cover the nose scaffold. Later, the nose was implanted into the man's forearm so that skin would grow to cover it.
Professor Seifalian said he and his team are waiting for approval from regulatory authorities to transfer the nose onto the patient's face but couldn't say when that might happen.
