Catching eyes when watching human cells are 3D printed with unprecedented technology

The future we can print 3D human organs seems very close.

The supply of human organs needed for transplantation is always in serious shortage, causing many people to disregard all moral and legal standards in order to find ways to trade illegally this item.

So when people think about a production revolution, they believe that this problem can be removed. Only thing, 3D printing a living cell is not easy, need more research time.

However, it seems that the future of human organs can be printed 3D is coming closer. According to a recent study from the University of Twente (Netherlands), experts have successfully developed a method to allow 3D printing tissue containing cells at extremely high levels of accuracy.

The future of human organs can be printed 3D is coming closer.

This new technique is called "in-air microfluidic" (temporarily translating "micro -air liquid") , consisting of two liquid-jet jet tubes. One side contains alginate, one containing CaCl ₂ .

2 spouts at the same time, so that the liquid collides in mid-air and then flows down to a swirling surface, thereby forming a tubular material. It is worth mentioning that this structure allows cells to be retained in the printing material.

After printing, the result is a multi-cell 3D tissue in the form of tubes. In other words, we will have a sponge-like structure, but made from hydrogels, and the inside is filled with human cells.

All details will be "revealed" in the video below the wire.

"This 3D printing model has the same internal structure as the natural tissue," explains the expert team.

"Many 3D printing technologies today use heat or UV rays - both damage living cells. This new method is extremely promising to produce living tissue in which living parts are The damage will be "corrected" by the material made from the patient's own cells. "

With the new method, science can control and shape tiny droplets of liquid - less than 1 micrometer. Moreover, the speed of new technology is much faster. Before that, we would have to take 17 hours to fill one centimeter of material, while now it only takes a few minutes.

It sounds very academic, but we should know about it, because this can be considered a revolution. In 2003, the first biological 3D printing technology applied in the US was simply an improved printer version, instead of printing ink, biological materials were printed.

Only a decade later, everything was like a leap. In 2015, science believes that it is possible to create a heart model thanks to 3D printing technology. And now, we are getting closer to the future of printing human organs, although there is still a lot of work to be done ahead.
