cardiovascular diseases The treatment methods developed for this are very diverse and as medical science progresses, these methods have become even more successful. Every year around the world almost 18 million People die of heart problems.

Scientists now have a vascular patency managed to develop a small, accurate model. Thanks to this research, an important basis has been created for new drugs, treatment methods and studies.

Significant treatment studies paved the way

Scientists from the University of Toronto and the University of Montreal have succeeded in creating a millimeter-long ship replica. In addition, this vein not only beats like in the heart, but also manages to pump fluid. That is, the pumping of blood throughout the body. simulate makes it possible. Human embryos have vessels of similar size.

biomedical engineer from the University of Toronto Sargol Okhovatianin a statement “Thanks to our model, we can measure the ejection volume, the amount of liquid that is pushed every time the vessel contracts. It was almost impossible to measure this in previous models.” say.

Under normal circumstances, there are not many alternatives to examining blood vessels. Or from cadavers after autopsy no longer works hearts are taken and examined or studies on biochemical functions are performed on tissue cultures. However, in these studies, the hydraulic structure of a three-dimensional and pulsating vein cannot be observed.

Ethical concerns can be omitted

While animal experiments can be used to see how a living heart will respond to treatment, ethical debates also come into play here. In the new study not fully developed Models developed with the 3D organic printer, which are: These studies use a combination of synthetic and biological materials.

The vessel developed by the researchers is the vein that emerges from the left ventricle of the heart and to the aorta It stands out as a copy of the blood-pumping vein. The cell, which consists of a three-layer cell structure, makes its natural throwing movement with the help of a special system. stimulation electricity is used.

The newly developed miniature ship has yet to be found in the human heart. up to 5 percent Although it can pump blood, it is considered an indication that the concept can be successful. A more layered and relatively larger model will pave the way for new studies. Research Advanced Biology was published in the magazine.
