MUNICH (Reuters)-
German researchers have created transparent human organs using a new technology that can pave the way for printing three organs
The size of the body such as the kidney used for transplant.
Scientists led by Ali Eltek of the University of Munich Ludwig Maximilian have developed a technology that uses solvents to make organs such as the brain and kidneys transparent.
The organs are then scanned by laser under a microscope, and researchers can capture the entire structure, including blood vessels and each single cell at a specific location.
The researchers used the blueprint to print out the stent for the organ.
They then load the 3D printer with stem cells that act as \"ink\" and inject the right position to make the organs functional.
While 3D printing has been widely used in the production of industrial spare parts, Erturk says this development marks a step forward for 3D printing in the medical field. Until now 3D-
Printed organs lack detailed cell structures because they are images based on computer tomography or MRI machines, he said.
\"We can see where each cell is in a transparent human organ.
We can then make a real functional organ using 3D bio-printing technology to replicate exactly the same . \"
\"So for the first time, I believe we are closer to real human organs.
\"Erturk\'s team is scheduled for the next 2-
3 years, also hope in 5-6 years.
The researchers will first test whether animals can survive through biological printing organs and can survive in 5-
Ten years, he said.
