Even yesterday, it applied to the realm of science fiction. Today, the latest technology of 3D-bioprintinga, or three-dimensional printing organs begin to develop in Russia.
On the technology company executives told 3D Bioprinting Solutions at the International Scientific Conference "Regenerative medicine in Russia", held on February 14 in "Hypercube" Skolkovo.
"We fill in the printer instead of the ink cells, and according to the computer model on a special substrate, we print in 2D-format. By printing layer by layer, we create a body in 3D-format ", — explained the idea of a three-dimensional biopechati (it biofabrikatsiya), professor at the University of Virginia, the supervisor of 3D Bioprinting Solutions Vladimir Mironov.
Printing unit bioprintere — not the individual cells and spheroids — conglomerates cells as balls placed in the hydrogel. But in order to print, spheroids should first do, and this is a separate problem that has been solved. Robotic devices produce such spheroids, dripping a suspension of cells in a microwell. They are made in different ways and the performance of them is also different. Record — 10,000 spheroids in a second. In order to print the body needs a "drawing" or "blueprints", in general, computer-aided design. Body — a complex structure consisting of different fabrics, filled with a network of blood vessels. Make a computer reconstruction of the kidney or the liver — the next stage.
Alexander Ostrovsky, co-chairman of the Board of Directors of the Company invitro and CEO of "3D Bioprinting Solutions", said at the forum held at the press conference that the development of this promising trend in Russian investors have already invested about $ 3 million.
Helena Livshits, director of medical programs, the Skolkovo Innovation Center, stressed that the biotech cluster innovation center, seeing the potential of this direction, decided to support scientific research and to facilitate the work of leading scientists.
The authors of the project said they are ready to make contact with the government, if the government decides to support the advanced development.
However, it became known thatRussian Defense Ministry has announced a tender for the development of transplantable bioengineered liver allocated for these purposes more than 518 million rubles and a half.
Development work on the creation of a body, which have been assigned code "Prometheus", must be completed before November 25, 2016. Until then, is expected to develop conceptual design, fabricate a prototype and conduct its tests, and then make the necessary preparations to launch mass production of bioengineered liver. Applications for participation in the competition are accepted until March 15, summing up its results is scheduled for March 20, 2013.
As indicated in the materials of the tender, the goal is to create a work intended for transplant patients with irreversible liver pathology bioengineering using the patient’s own stem cells for use in-hospital medical evacuation. Stem cells should be removed by taking the puncture in the patient from various sources, including bone marrow stroma and adipose tissue.
The prototype should have all the features and functionality of natural biological liver to detoxify xenobiotics, including, remove excess hormones from the body, vitamins, toxins, regulate carbohydrate metabolism, as well as replenish and store quickly mobilized energy reserves.
The composition of the product must enter frame liver stem cells from a patient, and growth factors — a molecule required for the growth of cells and tissues. With this method, obtain the structure of the liver should be clarified at the stage of conceptual design.
