With their new study of liver cells, scientists discovered that each liver is 3 years old, regardless of an individual’s age. This is possible thanks to long-lived cells that are rich in DNA.
While research is in full swing to learn more about our own body, scientists have made a new and surprising discovery. The new research, published in Cell Systems, revealed that no matter how old a person is, their liver is about 3 years old. In the study, between the ages of 20 and 84 Biopsy samples from 50 individuals examined.
While the rate of renewal and repair of cells decreases over time as our bodies age, new research indicates that this cells called ‘hepatocytes’ showed that it does not apply to Comparing the meaning-rich liver cells with other liver cells revealed significant differences in cell regeneration.
Cells with rich DNA can live up to 10 years:
Accordingly, while typical cells are renewed approximately once a year, it has been observed that cells rich in DNA can survive in the liver for up to ten years. While the rate of renewal of other cells decreases as we age, it is this feature of cells rich in DNA that protects us from accumulating harmful mutations. a protective mechanism It has been suggested that it might.
The discovery is a new and important discovery on the biological mechanisms that shed light on how our liver works. While it is very important for us to know the organs in order to protect ourselves from the disease in the future, scientists, on the other hand, in other organs such as the heart continues to examine how fast cells regenerate.
