Jerusalem - Tel Aviv University on Monday (April 15) presented a prototype of a miniature heart, which scientists say is the world’s first heart created with a 3D printer using human tissue.

“This is the first time anyone, anywhere, has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,” said Professor Tal Dvir, who led the research, which he presented at a press conference.

Until now, the university said, scientists have been successful in printing only simple tissue without blood vessels.

Dvir stressed the importance of the heart’s being made with a patient’s own cells and biological materials in order to eliminate the risk of implant rejection.

The heart, which journalists were able to view during the approximately three-hour-long printing process, is roughly the size of a rabbit’s heart.

“But larger human hearts require the same technology,” Dvir said.

The next step for the researchers is to culture the printed hearts in a laboratory and “teach them” to behave like hearts.

The current state of the primitive heart can be compared to the heart of an embryo.

“The cells need to form a pumping ability; they can currently contract, but we need them to work together,” Dvir explained.

Once they have achieved that, the scientists plan to transplant the hearts into small animals, such as rabbits or rats.

“Maybe, in ten years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely,” Dvir said.

The World Heath Organisation said last year that ischaemic heart disease and stroke were the world’s biggest killers.

Israel seems to have state of the art science facilities. So why is there health care so poor? Why are so many Israelis coming to the USA for doctors?

Why is your spelling so poor?
Why does the education in the USA cost so much and is worse than in Israel where it is free?

My bro Munch says it's because Israel works on cutting-edge new technologies and neglects tried and true basics.

My bro Munch says it's because they focus more on new technologies than on boring old medicine.

Education is not measured by ones spelling skills.
The USA didn't pay much for me since I went to private schools

Their healthcare is not poor, the Israelis live, on average, almost four years more than Americans. That said, they do not have the massive resources a country like the USA can bring to bear. That affects treatments and technology.

Education is partly measured by spelling skills, because spelling is part of education.

Longevity is not necessarily tied to health care. In fact people often turn to the fact that Deaths have risen recentley as a sign of our failing health care. There are many factors that go into our health care. Cancer deaths for example are way down. However, we have a drug epdimic that is not as bad in israel. We also have a high suicide rate. This is not directly connected to health care rather human behavior. Then there is also the unque factor in the USA that people live more spread out and far from hospitals.

Very minimual and almost not existent. Nowadays spelling is not a focus nor is it crucial. Business today is done via text like emails. The days of formal memos are gone. This includes at corporate America where I work. And we have many foreigners who can't speak the language either. It's really not a vital aspect to ones education any more unless he is a professor.

These are just the facts. Proper grammar and spelling are almost obselte. You are old fashion

Actually, due to spell checkers, spelling is considered a given, because almost everyone has the software built in.
