Americans are working on the technology of "printing" the skin with a 3D printer



A group of American scientists from the Institute of Restorative (Regenerative) Medicine at Wake Forest University (by the way, this is a fairly prestigious private university) recently announced its intention to create a reliable technology "bio printing". Scientists use for their research 3D-printers, which are becoming increasingly popular in the scientific community. At the time of its appearance, these printers were considered by many as quite interesting devices that would not receive practical use. However, everything turned out to be completely different: designers, builders, genetics and representatives of many other fields of activity began to use 3D printers in their daily work. A team of American scientists under the leadership of James Yoo (James Yoo) has long been working on the technology of "biopress", using biomass to create artificial skin, pieces of bones or cartilage.

So, scientists recently published a work that describes a successful experiment to restore a fragment of an animal’s damaged bone to a “printed” fragment on a 3D printer. Now scientists are trying to create a truly reliable method of “printing” human skin, because it is the skin that is one of the most popular organs (yes, the skin is the organ, and the largest in our body) in medicine. For example, it is very much claimed by burn departments of hospitals.

In addition, scientists plan to create a portable device that can work in the field. Such a device, according to the plan, should itself determine the degree of skin damage, determine, represent the information obtained in the form of 3D images, and analyze how many layers of cells should be replaced by artificial skin.

In fact, if this team succeeds, it will be close to printing more complex organs, bones and other parts of the body. As mentioned above, scientists conducted a fairly successful experiment with the replacement of damaged bone fragments of the animal.

All this sounds like science fiction, but every year more and more fantastic technologies appear that are already perceived without much surprise. Well, we will wait until scientists really learn to “print” organs.
