Recreate living organs with 3D printing

Both the medical technique of organ transplantation and 3D printing technology may have reached a milestone. Relayed in an American scientific journal, Experts Announce Successful Achievement of Printing Parts of the Human Body.

The very serious scientific journal Nature Biotechnology has just published an article which relates the experience of a team of American scientists from the Wake Forest Baptista medical center who has succeeded in fully recreating an ear using the 3D bioprinting technique.

It should be noted right away that this technology is not so far from conventional 3D printing. In other words, the method for printing a pen and the method for printing an ear are not so far apart. The latter proceeds to layer by layer assembly of the cells of biological tissues according to a predefined numerically scheme.

This feat has been done in the past, but so far the bones, muscles, or tissue produced by the printer were not strong enough or too unstable to be implanted in humans.

Organs that work after being implanted in animals

To prove how this technology works, scientists explained that muscles or printed cartilage worked normally after being implanted in animals. Proof for them that this technology offers real hope for all those awaiting transplants.

As regenerative medicine techniques advance, the number of people on the transplant waiting list continues to grow. Patients can wait several months or even several years before they can be treated. It will probably take several years to find conclusive results on humans, but this announcement has the merit of bringing a lot of hope to the medical community.
