According to Salk.Edu, US scientists at the Salk Institute of Biology have found that in the brain, the liver and pancreas of mice and cells and proteins exist almost throughout the entire life of the mouse.
It turns out, populations of the same cell in the internal organs are very different - some cells are very young, others have appeared almost since during the life of the organism.
The age of the cells is determined by the method of scanning using isotope imaging, so the image is high resolution.
In the course of the study, biologists have found some endothelial cells from blood vessels with age coinciding with age of nerve cells as well as beta cells of the pancreas and liver cells, with transverse age. with the age of the creature. Scientists believe this discovery opens up new opportunities for studying cell regeneration and aging therapy.
Professor Martin Hetzer of the research team explained that this shows that the complexity of the cell is even larger than we previously imagined and has a compelling meaning for how we think about aging. organs, such as the brain, heart and pancreas.
Most neurons in the brain do not divide in adulthood and therefore experience a long and age-related decline in life. However, mainly due to technical limitations, the lifespan of cells outside the brain is difficult to determine.
