The process of cell death is called apoptosis. In fact, for our body – this is a real “routine”, because every day for different reasons a person loses billions of cells. Apoptosis can be either with a plus sign or with a minus sign. In the first case, the body gets rid of cells that, for example, are capable of provoking cancer, but already healthy cells are destroyed in Alzheimer's disease.
A group of scientists from Stanford University, led by James Ferrel and Xianzhu Cheng, studied the death of Xenopus frog eggs in a microscope , which are in fact large living cells.
As it turned out, the process of cell death “starts” at the moment of damage to one of its sites, as a result of which a special chemical substance called “death signal” is released. It in turn provokes a kind of chain reaction – a “trigger wave” that spreads to neighboring parts of the cell, which also begin to emit such “deadly” signals. Thus, the mechanism of mass cell death is triggered. And so it will continue until the “death signal” finally becomes invalid.
Scientists managed to measure the “rate of cell death” – 30 micrometers per minute or 1.8 mm / hour. Understanding the process of self-organization of the cells of the human body, namely, the release of the body from cells that pose a danger to it, may further develop new methods of treating cancer, brain diseases and even prevent hair loss.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
