There was a potential success in laboratory organs. Israeli researchers have 3D printed heart, complete with muscles and blood vessels. But how long has it been prepared for actual use? Not long after, Dr. Max Gomez of CBS New York.
The printing of an organ is much more complicated than squirting a bunch of cells in the shape of a heart or kidney.
That said, researchers at Tel Aviv University made a major step toward off-the-shelf organs.
The video shows a living heart printed. 3D printing includes not only cellular cells, but blood vessels and other supporting structures. It's a little heart, about the size of a rabbit. Not only are cells alive, but all kinds of heart cell types come from a single human donor.
"That's important because it prevents the possibility of denial," says Dr. Anthony Atala of the Wake Forest Institute for
Dr. Atala is a pioneer in 3D printing of organs and tissues. He explained that cells produced by the heart came from the fat of a donor tissue, which was then changed to stem cells, and then different from different types of cell in the heart.
Cells are then printed in a biodegradable scaffold, or skeleton, giving it a shape
While it looks like a heart, structurally, it is not working and does not pump
"A functioning heart should contract and connected with working vessels, "The first printed organs and tissues for actual human use would be simpler: bladders, ears, blood vessels and windpipes, It is implanted in patients, according to Dr. Atala.
The more immediate value of Israeli work is to make what is called a cardiac patch, a piece of heart tissue function to repair damage to the heart attack.
The patch of the heart with inherent contracting ability, can be combined in the heart easier than building a whole heart that should contract in a coordinated manner. Atria and ventricles need to investigate in a specific order for blood to be pumped very well.
