German scientists create see-through ORGANS in step toward 3D-printed parts that could be transplanted in the human body

Researchers in Germany have created transparent human organs using a new technology that could pave the way to print three-dimensional body parts such as kidneys for transplants.

Scientists led by Ali Erturk at Ludwig Maximilians University in Munich have developed a technique that uses a solvent to make organs such as the brain and kidneys transparent.

The organ is then scanned by lasers in a microscope that allows researchers to capture the entire structure, including the blood vessels and every single cell in its specific location.

Using this blueprint, researchers print out the scaffold of the organ.

They then load the 3D printer with stem cells which act as ‘ink’ and are injected into the correct position making the organ functional.

While 3D printing is already used widely to produce spare parts for industry, Erturk said the development marks a step forward for 3D printing in the medical field.

Until now 3D-printed organs lacked detailed cellular structures because they were based on images from computer tomography or MRI machines, he said.
