Restored by toxins.
The forever young age of the liver was determined by scientists from the Technical University of Dresden. They wanted to know whether this organ retains its ability to regenerate over the years. The study confirmed: aging does not affect anything, informs Ukr.Media.
Not only biologists and clinicians, but also physicists and mathematicians participated in it. They studied the organs of people who died between the ages of 20 and 84. And in all cases, the liver cells turned out to be approximately the same age – no older than three years.
We will remind you that the liver is the main helper of a person in the fight against toxins, with its help the body is cleansed of them. For the gland itself, this does not pass without a trace: under the influence of poisonous substances, its cells are damaged and… regenerated again, thanks to the unique properties of regeneration. That is, thanks to the filtering of toxins, the liver remains forever young.
“Regardless of your age, the average age of your liver is just under three years,” explains Olaf Bergmann, the lead author of the study. – The process of its constant renewal is preserved even in the elderly.
At the same time, scientists noted: not all liver cells are of the same age. Some of them regenerate only after 10 years, and over the years there are more and more such cells.
"They have more DNA than typical ones: from 4 to 8 sets, scientists explain . – Perhaps this is a mechanism of protection against the accumulation of harmful mutations, a resistance factor to cope with cellular stress.
Now scientists plan to find out: whether a person has other organs , where cells are renewed at the same rate. They hope that thanks to their discovery, new ways of treating various diseases will appear.
By the way, normally hepatocytes, i.e. liver cells, are renewed every 150-500 days. And in 3-4 months, the liver can recover completely on its own, even if only 30% of it remains. Transplantists have long used this property in their work, dividing one organ between several patients.
