Austrian scientists have developed a tiny artificial heart, made up of living human cells, the size of a lentil and beats.
Although small artificial hearts, consisting of living human cells, have been made before, the highlight of this development is that the artificial heart cells have adapted themselves to this shape and the heartbeat. Started
Until then, experimentally as many tiny organs, including artificial hearts, were made, the number of living cells was increased by placing them in biochemical molds (scaffolds) with the required structure, even those molds. Would take shape while the material forming the template would dissolve and disappear.
Austrian experts used stem cells for this purpose while using certain biochemical reactions known as “pathways” technically. Is.
These pathways enabled stem cells to divide and transform, to regulate themselves, and to transform into tiny, throbbing hearts.
This method has previously been used experimentally in the preparation of small eyes and brains.
However, recent experiments have specifically identified pathways through which stem cells divide as well as change so that they can be converted into cells that activate a particular organ.

It should be noted that the heart is the first human organ which not only comes into existence after becoming pregnant but also starts doing its work first.
The formation of the heart in the mother’s womb begins on the 18th to 19th day, which also begins to beat and pump blood around the 22nd week of pregnancy.
