German scientists are getting closer to bioprinting real organs

Using a new bioprinting technology, German scientists can now create see-through organs!

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.

“We can see where every single cell is located in transparent human organs. And then we can actually replicate exactly the same, using 3D bioprinting technology to make a real functional organ,” he said. “Therefore, I believe we are much closer to a real human organ for the first time now.”
