Transparent human organs in 3D from Germany - Change16

A group of scientists from the Ludwig Maximilians University of Munich has developed a technique that allows to create human organs with more detailed cellular structures.According to Ali Erurk, research leader, the technique represents an advance in the medical field, since the creation of these organs were based on images of computerized tomography or images of magnetic resonance images.

The study, led by Erurk, is carried out by a group of researchers from the Institute for Research of Cerebrovascular and Dementia Accidents at the Medical Center of this German University.The real advance is the method used that makes the organs and even complete organisms transparent.

3D impression of human organs

3D printing is an emerging technology used in the creation of real objects from computer -produced models.From toys, jewelry, cars to food.The technique consists of depositing layer by layer "a liquid resin on a plaque until the desired object" obtained.

This technology has revolutionized the field of medicine, since if we change the "ink" we can obtain tissues and biological organs.Explain to communicate science that instead of using the plastic resin in the 3D printer, a biological ink produced based on stem cells is used.First, this cells must be cultivated and multiplied, and then be combined with a liquid medium.

This ink is loaded in the printer cartridge and the ink is deposited layer by layer following the pattern that dictates the printer.At the same time, a gel is placed that serves as a glue of the layers.When the impression is ended, the glue is extracted and the organ is obtained.There is also another process that consists in building organs by populating a biodegradable skeleton with cells with the shape of the organ that is desired: heart, liver, kidney, etc..

Closer than we thought

Communicate science and other media for 2015, indicated that the creation of organs such as a heart, liver or kidney could still take 20 years.Since the printing procedure is complicated according to the complexity of the organ that you want to reproduce.This same means as the Russian Laboratory 3D Bioprinting Solutions announced that by 2015 it would make the first transplant of a 3D organ.While American scientists claimed that by 2025 they would print the first human heart.

However, the challenge to be overcome in the impression of human organs is to work with organic materials.Mike Titsch, 3D Chief Editor Printer World, to CNN in 2014:

Each cell in place

The Ludwig Maximilians University Research Group of Munich has managed to develop a new bioimaging technology that provides information on nerve cell interactions in mammals and other organisms.

This new technology called VDisco makes the organs transparent and accessible to different image procedures.This technique is an evolution of a work presented in 2016 by the same team, Udisco.Udisco allowed the Erurck team to visualize in detail the nervous system of a mouse, however, the clarification technique was incomplete, since they were visible traces of bones and other tissues.

With Vdisco, the mixture of chemicals to clean the tissues has been modified, which allows completely transparent reproductions.This transparency of the tissues "allows visualizing and characterizing the total complexity of the nerve systems of small mammals, and will also allow researchers to track cell interactions that lead to inflammation and healing wound.

How does this apply to human organs?

The organ in question is scanned with a laser in a microscope that allows to capture its complete structure, including blood vessels and each cell.With this map, the body's scaffolding is printed.The 3D printer is loaded with biological "ink" produced from stem cells and injected into the correct position for the organ to work.

Erurk and his team plan the creation of a bio-impressing pancreas in the next 2-3 years.They also hope to develop a kidney.The most climax of this research is that researchers plan.
