In a north London 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.

In a north London hospital, scientists are growing noses, ears and blood vessels in attempt to make body parts using stem cells

"It's like making a cake," said Alexander Seifalian at University College London, the scientist leading the effort. "We just use a different kind of oven."

During a recent visit to his lab, Seifalian showed off a sophisticated machine used to make molds from a polymer material for various organs.

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 mold 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.

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

The potential applications of lab-made organs appear so promising even the city of London is getting involved: Seifalian's work is being showcased on Tuesday as Mayor Boris Johnson announces a new initiative to attract investment to Britain's health and science sectors so spin-off companies can spur commercial development of the pioneering research.

Ears, noses grown from stem cells in lab dishes

LONDON In a north London 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 US, that are working on the futuristic idea of growing custom-made organs in the lab.

While only a handful of patients have received the British lab-made organs so far including tear ducts, blood vessels and windpipes researchers hope they will soon be able to transplant more types of body parts into patients, including what would be the worlds first nose made partly from stem cells.

Its like making a cake, said Alexander Seifalian at University College London, the scientist leading the effort. We just use a different kind of oven.

The polymer material Seifalian uses for his organ scaffolds has been patented and hes also applied for patents for their blood vessels, tear ducts and windpipe. He and his team are creating other organs including coronary arteries and ears. Later this year, a trial is scheduled to start in India and London to test lab-made ears for people born without them.
