Blood of young mice has the uncanny power to slow aging in old mice.
: The young and old mice share much more in this procedure. For example, old mice have access to the younger organs and the mice exchange blood factors in both ways so that the damage accumulated with age is distributed, together with other factors that might influence biological age.’Generally, parabiosis experiments last for only a month or 45 days.
They noticed that during the time the mice were connected the young mouse was aging faster. However, after it got separated from the old mouse, theThe most surprising changes were observed in the old mouse though. Heterochronic parabiosis reduced the aging of blood cells and liver tissues in the mouse and triggered genetic changes that promoted longevity.
“The older mice became younger, and they lived longer than the controls. The difference in lifespan is significant,” said Gladyshev. Therefore, these findings suggest that if old mice share a common circulatory system with young mice for a long time, they are also likely to experienceInterestingly, if you apply the logic from this study to human aging, you may assume that the same process couldof a person by nearly six years . However, that’s not how logic and science work. Gladyshev and his team are still not sure what caused the increase in the old mouse’s lifespan.
