Researchers from Oxford report: they managed to successfully print a three-dimensional structure of living cells. This experiment opens the way to the creation of a universal platform for 3D printing of living tissues, with the prospect of recreating a synthetic analogue of any part of the human body.
The problem with working with living cells is that they tend to shift during printing and are prone to spontaneous suicide. To prevent this from happening, Oxford scientists decided to wrap each cell in front of the 3D seal in a personal lipid coating. It turns out a kind of “brick” – a very convenient element for the compilation of various designs.
3D-printer for living tissues functions identically to devices for working with polymers, but the printed circuits themselves are completely different. It is necessary to take into account that the finished product will not be stable, it must live, grow, and various biological processes will flow in it. Otherwise, the result will be a useless piece of synthetic flesh .
The technology of printing a fragment of a body or a whole body based on the DNA of a particular person opens up new biomedical opportunities for scientists. So, it can be tested for compatibility with allergens, drugs, toxins, irradiation or poorly studied substances, without exposing the patient himself. In the future, 3D printing of living tissues can become a new branch of regenerative medicine.
