Scientists in the United States have made the latest discovery: Stem cells can extend life twice as

Scientists in the United States believe that stem cells contain proteins that may hold the key to rejuvenating the body. Researchers from the university of Pittsburgh say further research may give us hope that we may be able to completely delay the aging process.

Research by us scientists has found that stem cells can delay ageing and even extend life by up to three times.

Experiments on mice at the university of Pittsburgh have found that progeria mice can live longer and even grow bigger and stronger if stem cells from young mice are injected.

Experiments in laboratories by American scientists have shown that the condition of progeria cells improves markedly when young stem cells are placed side by side with progeria cells.

Scientists in the United States believe that stem cells contain proteins that may hold the key to rejuvenating the body. Researchers from the university of Pittsburgh say further research may give us hope that we may be able to completely delay the aging process.

Researchers at the university of Pittsburgh in the United States began the study by manipulating mice to show signs of early aging. Studies of these mice showed that their stem cells did not regenerate as quickly as those of normal mice.

Then, when researchers injected stem cells from young mice with early-aging problems at 17 days old, their life span tripled from an average of just 21 to 28 days to more than 66 days.

The prematurely aged mice grew as strong as healthy mice after being injected with healthy stem cells.

Dr. Niedenhofer, of the university of Pittsburgh, United States, said, "when stem cells are injected into young, healthy mice, mice that already had premature aging become healthier and live longer."

Scientists believe this is because healthy stem cells help repair malformed stem cells in rapidly aging mice.

"What this tells us is that stem cell dysfunction is one of the causes of aging changes," Dr. Needenhofer said. “As mice with premature aging age, they lose muscle mass in their hind legs, which can lead to body bending, body shaking and slow movement.”

When the affected mice were injected with stem cells just before they started showing signs of aging, they became more like normal mice and grew almost as big, Dr. Niederhoffer said.

Further examination by the researchers also found that the affected mice developed new blood vessels in their brains and muscles, but there were no signs of foreign stem cells in those areas, she said.

"In fact, when stem cells were injected into the abdomen of the affected mice, they did not migrate to other parts of the mice."

"We therefore hypothesize that mysterious factors in the alien healthy stem cells create a favorable environment to help modify the function of the original stem cell population and aging tissue," she said.
