For the first time, scientists have managed to create stem cells from the cells of an 114-year-old woman, who is also the oldest donor so far.
The cells were taken from a blood sample and returned to the stem cell level. After that, these stem cells were successfully used for the regeneration of certain tissues such as bone, cartilage and adipose tissue.
We have now proven that this can be reported and we have a valuable tool for finding genes and other factors that can slow down aging, said one of the participants in the research.
Of course, the most valuable cells are those that are collected at birth, but their procurement raises some ethical questions. Fortunately, it has been shown that cells taken from adults, the so-called somatic cells, can be brought to the stem cell stage.
Until now, it was not known how long human cells remain in a state in which they can return to the level of stem cells. After numerous failures, experts have succeeded in reprogramming cells that originate from people older than 100 years.
It has been shown that people who are over a hundred not only age more slowly, but also have a strange immunity to age-related diseases, such as Alzheimer’s or Parkinson’s disease. In addition, this immunity seems to have nothing to do with lifestyle. This is a new topic of examination, to discover what it is that prolongs life so much.
Currently, only 28 people over the age of 110 are known. However, this population is difficult to study, both because of the small number and because in some cases it is not possible to determine the age with certainty.
