Scientists rejuvenate human cells
A group of scientists at Stanford University succeeded in rejuvenating human cells for the first time in history, according to the journal Nature.
To do this, they used the mechanism used to create stem cells. With the help of special RNA, they forced the cell to produce the so-called. factors Yamanaki – a special protein that plays an important role in the formation of embryonic cells.
If this procedure is applied to a normal cell for 2 weeks, an induced pluripotent stem cell will be obtained. Scientists have tried to shorten this period to eliminate the negative factors causing aging by using the method for only a few days.
During the experiment, it became clear that the cells were actually “rejuvenated” – by many signs were indistinguishable from their younger counterparts.
The pattern of gene expression has changed – the most harmful strands of DNA during adolescence are restrained by control systems that weaken over the years. The use of Yamanaki factors has allowed this process to be reversed in practice.
