Pig has successfully transplanted lab-grown lungs

University of Texas, Department of Medicine, Bioengineering Laboratory - from here came the news of the successful completion of an experiment to transplant man-made pig lungs. This takes the bioengineering industry to a new level, when, according to the most optimistic forecasts, we will learn to copy all internal organs within a decade. And we can start creating them for humans.

The cultivation of new lungs for pigs began with the creation of a base, for which ordinary lungs were taken from a donor, from which all living cells and blood were removed. It was simply washed long and thoroughly with a mixture of cleaning agent and sugar until only a tough protein frame remained. Then he was placed in a cell with nutrients and they began to plant live cells from the lungs of pigs on the frame, which were to receive them.

In almost ideal conditions, the cells grew rapidly, already in the second week they themselves formed the blood vessels they needed, and by the 30th day, the new lungs were ready. All four prototypes were transplanted into guinea pigs, similar to organ donation. The lungs took root, and observation for two months did not reveal any immune response, because the grown lung tissue was actually its own, "native". Now the next step is a long-term experiment - you need to study the work of these lungs for several years.

The success of the Texas scientists reinforced their belief in the main concept of bioengineering - growing large fragments for transplantation from several cells of the body itself eliminates the problem of the immune response. With the proper level of technology development, it will be enough to conserve small tissue samples of all organs of a person who is sent to an extreme situation, in order to compensate him for the loss of any part of the body in a few months. Except for the brain - but work is being done in this direction as well.
