Newer study: People produce new cells throughout their lives

People continue to produce new neurons in a part of the brain that includes learning, memory, and emotions, throughout their lives, the scientists discovered, opposing previous theories that their numbers stop after adolescence.

Many of the new neurons are produced in the hippocamps during the infancy, but it has been a matter of hot debate if this continues in adulthood and, if so, if so, falls by age as seen in rats or nonhuman primats.

However, some studies have found that new neurons have developed in older people, says the latest study, assuming that new neurons in the hippocampus were unrecognitionable until adolescence, reports The Guardian”, broadcast Periscope.

Now another group of scientists have published research that undermines this theory, finding that new neurons are produced in this region of the brain in human adults and are not reduced when age grows. The findings may, according to researchers, provide good conditions for creating better treatment of Alzheimer's disease and other psychiatric problems.

The exciting point is that neurons are there throughout life”, said Dr Maura Boldrin of the University of Colombia in New York and the first author of the new study published in “Cell Stem Cell”. It seems that people are actually different from rats where [the production of neurons] comes down with age when it grows, and that means we need these neurons for the complex learning skills and cognitive reactions to emotions”.

Boldrin and her colleagues looked at the hippocampus of 28 men and women between the ages of 14 and 79, gathered only a few hours after their death. Importantly, Boldrin points out, all individuals were healthy before death, unlike many previous studies.

Using a number of techniques, the team examined the scale of the formation of new blood vessels, the volume, and the number of cells during various stages of maturity, in an area known asgyrus dentates ) the hippocampus region, where new neurons are produced.

“According to mouse studies, there are these pluralant stem cells that are a bunch of cells that normally don't do anything, they are quiet and then they can submit to the divide”, Boldrin said, adding that some studies have suggested that they could give birth to an endless array of cells known as cell cells.

The team found that the levels of these <x0-cells of the mother” dropped as the age in the front and middle part of the detete zurus increased. However, the cell levels they produce do not decrease, with the team finding thousands of new ones./Periscopi/
