A woman aged 115 years reveals its secrets related to longevity. You want to live as much as she? Learn what to do in this regard.
Van Andel-Schipper When Hendrikje donated his body for the sake of science, she gave them longevity researchers in a truly special gift. She was the oldest person in the world when she died at age 115 years, and her body found in the hands of a team of Dutch researchers has launched a lot of groundbreaking investigations in an attempt to find an answer to the question why some people live longer than others.
In 2010, scientists led by Dr Henne Holstege of the VU University Medical Center in Amsterdam analyzed genomes (the total weight of genes and other hereditary information) woman named Hendrikje Van Andel-Schipper, hoping to discover the secrets of longevity her genes.
In the latest study Dr Henne Holstege, published in the journal "Genome Research", the researchers looked for mutations occurring in the blood of women for 115 years. When stem cells divide, they generate different types of blood cells such as white blood cells. But these cell divisions can also cause mutations.
So scientists have wanted to determine if mutations can occur in healthy white blood cells over time and whether they have any impact on health. They found that although the woman was 115 years, in large part, a healthy person, there were hundreds of genetic mutations in its cells, which the scientists found it curious. So they continued to explore from where these white blood cells and their stem cell focused on the woman in question.
Researchers estimate that each individual begins life with nearly 20,000 stem cells, of which 1300 are considered "active". To the surprise of scientists, a woman of 115 years, Van Andel-Schipper Hendrikje had only two active stem cells at the time of his death. "At first I could not believe this was true. I thought it must be a technical error. Could not be true that this person can be alive with only two stem cells," says the doctor who led the study, Dr. Holstege.
Then researchers turned their attention to telomere length (a region of repetitive DNA located at the end of each linear chromosome) from the blood cells of women for 115 years and found that they were extremely short telomeres compared to all other organs of women.
As the cells grow older, their telomeres shorten. Therefore, researchers have realized that there may be a limit to the number of divisions on our stem cells can do and that at some point, the stem cells must begin to die from exhaustion process of division.
It is possible that stem cell exhaustion may have been the cause of death of women for 115 years and at the same time, this could be the cause of death among people living to old age, although researchers admit that more studies should be done to determine if this is true.
Although there are several factors worthy of consideration in this game against the clock, new research suggests you should probably consider stem cells and to think that they might be one of the secrets to have a longer life.
