So what did the Bible, God's word, say, thousands of years ago, about life being in the blood? RB
_____________________________________________
Holy Scripture
Old Testament Blood sacrifices of animals pointed forward to God's sacrifice of the Lamb of God, Jesus Christ, His Son, in the New Testament, for our sins.
"For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul." Lev.17:11.
The New Testament Sacrifice of the Lamb of God, Jesus Christ, is the fulfillment of Old Testament, blood sacrifices of lambs, doves and heifers, which were simply preview types of the coming Lamb of God, the prophesied Messiah.
"And almost all things are by the law purged with blood; and without shedding of blood is no remission." Heb.9:22.
"So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation." Heb.9:28.
So, after 3,504 years, what has the
world of science now discovered
about life being in the blood? RB
Young Blood May Hold Key to Reversing Aging
Two teams of scientists published studies on Sunday showing that blood from young mice reverses aging in old mice, rejuvenating their muscles and brains. As ghoulish as the research may sound, experts said that it could lead to treatments for disorders like Alzheimer’s disease and heart disease.
“I am extremely excited,” said Rudolph Tanzi, a professor of neurology at Harvard Medical School, who was not involved in the research. “These findings could be a game changer.”
The research builds on centuries of speculation that the blood of young people contains substances that might rejuvenate older adults.
In the 1950s, Clive M. McCay of Cornell University and his colleagues tested the notion by delivering the blood of young rats into old ones. To do so, they joined rats in pairs by stitching together the skin on their flanks. After this procedure, called parabiosis, blood vessels grew and joined the rats’ circulatory systems. The blood from the young rat flowed into the old one, and vice versa.
Later, Dr. McCay and his colleagues performed necropsies and found that the cartilage of the old rats looked more youthful than it would have otherwise. But the scientists could not say how the transformations happened. There was not enough known at the time about how the body rejuvenates itself.
It later became clear that stem cells are essential for keeping tissues vital. When tissues are damaged, stem cells move in and produce new cells to replace the dying ones. As people get older, their stem cells gradually falter.
In the early 2000s, scientists realized that stem cells were not dying off in aging tissues.
“There were plenty of stem cells there,” recalled Thomas A. Rando, a professor of neurology at Stanford University School of Medicine. “They just don’t get the right signals.”
Dr. Rando and his colleagues wondered what signals the old stem cells would receive if they were bathed in young blood. To find out, they revived Dr. McCay’s experiments.
The scientists joined old and young mice for five weeks and then examined them. The muscles of the old mice had healed about as quickly as those of the young mice, the scientists reported in 2005. In addition, the old mice had grown new liver cells at a youthful rate.
The young mice, on the other hand, had effectively grown prematurely old. Their muscles had healed more slowly, and their stem cells had not turned into new cells as quickly as they had before the procedure.
The experiment indicated that there were compounds in the blood of the young mice that could awaken old stem cells and rejuvenate aging tissue. Likewise, the blood of the old mice had compounds that dampened the resilience of the young mice.
Amy J. Wagers, a member of Dr. Rando’s team, continued to study the blood of young mice after she moved in 2004 to Harvard, where she is an associate professor. Last year, she and her colleagues demonstrated that it could rejuvenate the hearts of old mice.
To pinpoint the molecules responsible for the change, Dr. Wagers and her colleagues screened the animals’ blood and found that a protein called GDF11 was abundant in young mice and scarce in old ones. To see if GDF11 was crucial to the parabiosis effect, the scientists produced a supply of the protein and injected it into old mice. Even on its own, GDF11 rejuvenated their hearts.

Dr. Wagers and her colleagues wondered whether GDF11 was responsible for the rejuvenation of other tissues. In the current issue of the journal Science, they report an experiment on skeletal muscle in mice. They found that GDF11 revived stem cells in old muscles, making old mice stronger and increasing their endurance.
At Stanford, researchers were investigating whether the blood of young mice altered the brains of old mice. In 2011, Saul Villeda, then a graduate student, and his colleagues reported that it did. When old mice received young blood, they had a burst of new neurons in the hippocampus, a region of the brain that is crucial for forming memories.
In a study published Sunday in the journal Nature Medicine, Dr. Villeda, now a faculty fellow at the University of California, San Francisco, and his colleagues unveiled more details of what young blood does to the brains of old mice.

Hebrews 9:14 - How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
The best kind of transfusion!
