Israeli scientists 'print' world's first 3D heart with human tissue

A team of Israeli researchers has “printed” the world’s first 3-D vascularized, engineered heart.

On Monday, a team of Tel Aviv University researchers revealed the heart, which was made using a patient’s own cells and biological material. Until now, scientists have successfully printed only simple tissues without blood vessels.
“People have managed to 3D-print the structure of a heart in the past, but not with cells or with blood vessels. Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future,” he said.

At this stage, the 3-D heart produced at TAU is sized for a rabbit, but the professors said that larger human hearts could be produced using the same technology.

For the research, a biopsy of fatty tissue was taken from patients, according to a release. The cellular and a-cellular materials of the tissue were then separated. The cells were reprogrammed to become pluripotent stem cells that could then be efficiently differentiated into cardiac or endothelial cells. The extracellular matrix (ECM), a three-dimensional network of extracellular macromolecules, such as collagen and glycoproteins, was processed into a personalized hydrogel that served as the printing “ink.” The differentiated cells were then mixed with the bio-inks and were used to 3D-print patient-specific, immune-compatible cardiac patches with blood vessels and, subsequently, an entire heart.

According to Dvir, the use of “native” patient-specific materials is crucial to successfully engineering tissues and organs.

The next step, they said, is to teach the hearts to behave like human hearts. First, they will transplant them into animals and eventually into humans. The hope is that within “10 years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely,” Dvir said.
The future is here.

I don't care where (just far)
This is amazing.

It was a few years ago I heard some podcast where an expert was saying that within 15-20 years or so we will be able to 3D print most anything to help a body survive except the brain.

I love reading about advancements like this that will hopefully save countless lives. This type of science is heroic

I saw another vid recently of someone printing a cooked "steak".

3D printing is going to revolutionize the world and probably within our lifetime. We are approaching star trek level shit.

Can they 3D print my love for AOC so it can be preserved forever and duplicated for generations to come?

(No but for real, really amazing stuff. Glad you posted this.)

Did not understand anything in the article other than the headline but cool and good for humanity.
