How does this sound? An injection that would make a sixty year old person feel like they were twenty again! Well this would be the equivalent of the results so far achieved by scientists experimenting with NAD ( nicotinamide adenine dinucleotide).
They claim to have moved the ‘aging markers’ in two year old mice back to six months by injecting a naturally produced substance that reverses the breakdown in communication that occurs between types of cells during the aging process.
But don’t get too excited just yet. They are only in the early stages of experimentation, and so far, decrepit mice of the grand old age of two are the only beneficiaries of this new lease of life. But tests on humans are immanent, and any side effects are expected to be low grade or non-existent. Who wants to look twenty with a nice long silky tail and pointy ears ? !!
Researchers on NAD in the U.S.A. and Australia are looking way beyond the cosmetic possibilities of this idea to see if the process can also be useful in the treatment of dementia, cancer, and diabetes.
Experts in ‘stem cell’ technology at the McGowan Institute for Regenerative Medicine in Pittsburgh, U.S.A. have been amazed by results achieved with the injection of muscle stem cells into mice.
Stem cells from the muscle apparently have the unusual ability to reproduce identical cells in other parts of the body. Researchers were more than surprised to find that mice which had been given a life shortening condition had there lives extended by three times the expected age after receiving this treatment.
Repeated experimentation has produced something of a mystery. Researchers had expected that the new introduced stem cells were improving the function of vital organs, but tracking of the cells disproved that theory. Instead, it seems that the fresh cells secrete something which rejuvenates all surrounding cells.
If the secretion can be isolated and identified, this will effectively move onward experimentations for anti-aging, with other repercussions for the healthier lives of humans. In the meantime, the rodent community seem to benefit again.
