The longest living cell in human body are those responsible for vision.
Scientists from the Karolinska Institute of Medical and Surgical Sciences in Stockholm have measured the age of various cells in the human body. To do this, they modified the radiocarbon method, which has long been used to determine the age of archaeological finds. Studying fragments of tissues taken from the remains of several people, scientists concluded that the cells of the area of the cerebral cortex, which is “responsible” for vision, live the longest in the human body. Their age is equal to that of a person. Cells of the intestines and spine live about 10 years, and blood cells change every few months.
According to the authors, determining the lifespan of cells in different organs and tissues will enable a better understanding, for example, of the role of apoptosis (programmed cell death) in various disorders of consciousness. Earlier, a previous study had found that a failure in the cell regeneration mechanism of some brain tissues causes deep depression.
