Immortality is the eternal dream of mankind

Among many attempts, blood from young animals seems to have a certain effect

Today, the “Nature” sub-Journal “Nature-Aging” published a paper, revealing to us a major reason behind it

Specifically, the researchers studied muscle tissue

In order to study the underlying mechanism, the team separated plasma from the blood of young mice and injected it into older mice with muscle damage to observe their changes

What kind of ingredient is so magical? Further screening found that if the extracellular vesicles in the plasma were removed, the plasma would suddenly lose its effect and no longer promote muscle repair in elderly mice

Analysis in these vesicles revealed that they contained an mRNA encoding Klotho protein

According to their vision, in the future, we may be able to add more specific molecules to these intracellular vesicles, let them locate in different stem cells, and restore the activity of these stem cells
