This was stated by Vladislav Parfenov, Head of the Scientific Projects Implementation Group of the Science and Innovations Corporation, a subsidiary of Rosatom, on the sidelines of the 11th International Technological Development Forum “Technoprom-2024”, currently being held in Novosibirsk, Western Siberia.
“We are now developing the technology of growing vessels and plan to grow a vessel up to 10 centimeters long, then we will start animal experiments, and after that we will work on developing technologies for growing complex branched systems, and I think that by 2030 we will be able to achieve this and move on to complex human tissues, such as the thyroid, kidney and liver,” Parfenov said.
According to the scientist, to create living tissues, a unique non-contact technology based on the operation of physical fields is used. This technology does not require the use of additional materials other than the patient’s cells, which makes it possible to ensure high biocompatibility with the human body and achieve the desired tissue properties. In order to grow functional blood vessels of small diameter, the patient’s cells are placed in a bioprinter, where they are given the desired shape using magnetic fields and ultrasound.
“Then the cell fusion processes begin, thanks to which a single tissue is formed. After that, the process of ‘maturation’ begins inside the bioreactor, that is, the cultured vessel receives the necessary properties similar to human tissue,” Parfenov continued.
It is noteworthy that last February, a magnetic acoustic bioprinter was demonstrated, which is used to grow tubular tissues under the influence of physical fields, in addition to a bioreactor, in which the vessel “learns” to work correctly. These technologies were demonstrated to Russian President Vladimir Putin during his visit to the Future Technologies Forum.
