American scientists find that injection of stem cells can increase life expectancy by 3 times

One study confirmed that the life span of mice was extended by three times when they were injected with stem cells. Scientists believe that studying the proteins in stem cells may be the key to providing humans with "immortal" injections. Scientists say that stem cells can interrupt the aging process and even extend their life span by a factor of three. One study confirmed that the life span of mice was extended by three times when they were injected with stem cells.

Scientists say that stem cells can interrupt the aging process and even extend life expectancy by a factor of three. One study confirmed that injecting stem cells once provided a three-fold increase in the life span of mice, and it would make rats grow bigger and stronger.

Scientists believe that studying the proteins in stem cells may be the key to providing humans with "immortal" injections. Further research by researchers at the University of Pittsburgh will help us delay the aging process. This effect can be seen even on cells in laboratory vessels, where they place young stem cells side-by-side with prematurely aging cells. When patients' senescent cells are placed next to healthy cells, their efficacy will be better. Researchers in the United States conducted research on mice that had undergone modified premature aging (known as premature aging). Humans also have premature aging.

Researchers began to inject stem cells from these young mice when they were healthy, extending their lifespan to three times that of those who were old. Their experiment was the first stem cell study on the victims of premature aging. Scientists have discovered that the cells in these mice are different from those in early-senile mice, which are smaller and have slower regeneration than normal mouse stem cells. However, the injection of stem cells into 17-day-old mice showed that their lifespan was significantly longer, extending from an average of 21 to 28 days to more than 66 days, which was 3 times longer than usual.

After injecting stem cells to improve mice, they grow almost as well as healthy mice, and new blood vessels grow in the brain and muscles. Scientists believe that this is because healthy stem cells can help correct the changes that occur in the cells of aging mice. The research was published in the journal Nature Communications. Dr. Laura Nitton Hoefer said: "Our tests show that if aging rats start younger and healthy when they inject stem cells, they will live healthier, Longer life. This shows that stem cell dysfunction can cause aging."

Nitton Hofer said: "As the age of older mice increases, their hind leg muscles will decrease, and they will experience hunched back, trembling, sluggishness, and awkwardness. Affected rats should have the first sign of aging After injection of stem cells, they will be more like normal mice and grow almost as large as normal mice. Further studies show that these mice also grow new blood vessels in their brains and tissues, even if stem cells are not found in these tissues. This is also the case. In fact, after stem cells were injected into the abdomen of rats, they did not transfer to any specific tissues."

“This leads us to believe that the environment created by the secretory factors of healthy cells helps to correct dysfunctions of indigenous stem cells and aging tissues. In a petri dish test, we put young stem cells on the side of premature aging cells, but two The person did not come into contact and found that the function of unhealthy cells increased significantly."
