The heart was first cultured from stem cells

Researchers at Kyoto University cultivate heart cells, creating a new breakthrough in medicine.

>>>Culturing human heart

The group of Japanese geneticists headed by a Russian scientist, Konstantin Agladze, for the first time cultivated a living human heart from stem cells. The work was carried out in a laboratory of Kyoto University.

The group of scientists at Kyoto University is headed by Professor Agladze.

According to experts, this result could fundamentally change the not only views on transplantation, but also on the pharmaceutical industry.

The team said the fetal stem cells at the early stage of development are a source of genetic materials. From stem cells grow into organs in the body. According to geneticists, the main goal of the study is to determine the conditions for forming any tissue.

At Kyoto University laboratory, scientists have found a chemical that activates the metabolism mechanism. Of the 100 induced protoplasm cells, 80 became cardiac cells. They also found the optimal temperature to preserve cells is about - 37 degrees C.

Konstantin Agladze said: "The heart's structural tissue we created has two fundamental advantages. First, we can easily check the effect of different substances. Second, we can use nanofibers of these cells to transplant into a damaged heart '.

To show that true heart cells live, it is placed under an electron microscope with a magnification of several million times that it is very clear that the tissues shrink and stretch (50-70 beats per minute). and the heart muscle works without stimulation from the outside.

In addition, the researchers studied the effects of different substances on heart cells, using nanofibers implanted in the hearts of some seriously ill people with less ability to survive.

In addition, the study of this group of scientists is not only limited to the heart but also to other organs in the body, first of all kidneys.
