Scientists say they created the first 3D print heart in the world – Hack



We move one step closer to a future where doctors can only twist the replacement organs made from your own cells, with Israeli researchers expressing that they have only 3D printed with a whole heartbeat with biological materials

you need a heart transplant, you have to wait for an available and appropriate organ from the other person's body, and the organs do not always last .

This week, scientists from Tel Aviv University in Israel announced that they made progress toward Alternative Solution

Using a bio-ink gel derived from the fatty tissue "reprogrammed" as stem cells , they are 3D prints of a tiny, heart heart for three hours.

"This is the first time anyone has been successfully recorded and printed with a full heart full of cells, blood vessels, ventricles and chambers," said Tal Dvir's author in a statement from university.

The heart, about the size of the rabbit, is too small for a man, and the researchers are still figuring out how it's bent

But the process used to create it shows potentially for a day to be able to 3D print patch and possibly full transplants, Professor Dvir said.

He said that it may mean that patients will no longer have to wait for transplants or take drugs to suppress their rejection.

"Instead, the required organs will be printed, fully personalized for each patient." "Perhaps, in ten years, there will be organ printers in the world's finest hospitals, and these procedures are performed regularly."

Making a chemical heart, it started

According to research published in German Wiley-VCH notes, researchers used fatty tissue taken from b

Cellular materials of the issue were then isolated and the cells were genetically "reprogrammed" to become pluripotent stem cells – these are cells that can result in all types of cells that make up the body.

The remaining cells are processed in a "thermoresponsive hydrogel" which becomes stronger in heating the temperature of the human body (37C).

The mixture of hydrogels and stem cells was injected into 3D printers cardiac tissue based on anatomical data from CAT scans.

" Ideally, biomaterials should have the same biochemical, mechanical and topographical features of the patient's own tissues.

Technology can also be used to make "vascularised patches" to replace parts of the organs – similar to the way you replace parts of a car engine.

To show how accurate hydrogel can be accurately, high-resolution thick structures, 3D researchers-printed by human hands (this does not include internal parts such as bone and blood vessels).

The design for the hand is downloaded from the website Thingiverse – a creative data design designs for 3D-printed objects.

Printing of a human heart is much more complicated than the size of the thumb, but Professor Dvir says that in many cases it is not necessary to replace the whole heart – instead, we can simply remove and re- patch the sick areas.
