German artists invent technology that makes body members transparent

Researchers in Germany have made the human body transparent using a new technique that could pave the way for the printing of three-dimensional parts of the body - such as kidneys - for transplants.

They have been able to produce transparent and rat-like human organs, a step that can pave the way for the production of organs such as kidneys with 3D printing technology that are later used in transplantation.

Scientists aim to identify the exact structure and components of human organs in order to "copy" them later with three-dimensional printing.

The team of scientists at Ludwig Maximilians University in Munich - led by Arturk - developed a technique that uses a solvent to make organs such as the brain and kidney transparent.

Technical organic solvents are used to strip cells of fat and dyes but retain their structure within them. A laser scan is then performed in a microscope that allows the researchers to depict the entire organ's structure, including blood vessels, and locate each cell in it.

Using this survey, the researchers type an external structure of the organ, then put stem cells into the 3D ink machine, which is called "ink" and then injected in the right place and makes a member capable of performing its functions.

"3D imaging is a step forward for 3D imaging in the medical field," said Arturk, who believes that 3D printing devices - now available - have detailed cell structures because they are image-based From computer tomography or from magnetic resonance imaging (MRI) devices. "

He added d. "We can - with the new technology - see where each cell is located in transparent human organs, and then we can accurately copy it using 3D printing technology to make a real functional member," he said, "so I think we are now much closer to producing a real human Once".

The research team - which developed the new technique - plans to start creating a biologically-printed pancreas within the next two to three years and also hopes to develop entirely in five to six years.

The researchers will first test whether animals can survive with biologically printed organs and can begin clinical trials in humans within five to 10 years, Artwork said.
