American scientists created a tiny artificial heart
World
Scientists at the Cedars-Sinai Medical Centre in Los Angeles (USA) have created a special chip capable of performing the functions of a human heart. This nanotechnology can be used in the treatment of various diseases.
In particular, the tiny device is very useful in research and trials of cancer treatment. That is, it allows you to study the work of the heart in detail, as well as to check its condition during the disease.
In addition, new drugs, especially drugs against cardiovascular diseases and advanced therapies, will now be tested on this "chip-heart" rather than on experimental animals.
Induced pluripotent stem cells - regenerative tissues - were used to create the device. Some of them form muscle tissue and the rest form blood vessels.
For example, muscle tissue contracts at 60 beats per minute, like the human heart, and can work continuously for weeks.
"The researchers believe that although this chip cannot yet replace a real heart, its use as an 'experimental mouse' in medical practice is effective," writes the press service of the Ministry of Health.
