German scientists create see-through human organs

Dr. Ali Erturk, Group Leader at the Institute for Stroke and Dementia Research (ISD) at the Ludwig Maximillian's University, looks at a transparent human brain at his laboratory in Munich, Germany April 23, 2019. 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.

An employee checks the 3D printing of a scaffold for a kidney. 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.

A transparent mouse is pictured at the laboratory of Dr. Ali Erturk. Until now 3D-printed organs lacked detailed cellular structures because they were based on images from computer tomography or MRI machines, he said. "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."
