Editor-in-Chief Irina Conboy, PhD, Professor, College of Engineering, University of California, Berkeley says “This work clarifies the concern of whether the young blood or old blood control durability, which has actually been debated (Nature 2005, Conboy, et. The work by the Pishel group developed that the life expectancy of the old mice does not increase after being parabiosed to young mice.
” This discovery is very important in developing the accurate direction for medical anti-aging methods and in supplying essential scientific proof versus the potency of the young blood factors in an aged organism. This work neatly follows the report previously published by this group that infusions of young blood plasma into mice do not increase their lifespan.”
On a really important note, Professor Pishel conducted these critical research studies as the Head of the Department at Kyiv National Taras Shevchenko University, yet made up the paper as a refugee, from data gathered before the outbreak of war with Russia. Such important studies were disrupted by the war, and we hope that the research will quickly continue and yield more breakthroughs.
Referral: “Three Month Heterochronic Parabiosis Has a Deleterious Effect on the Lifespan of Young Animals, Without a Positive Effect for Old Animals” by Tatiana Yankova, Tatiana Dubiley, Dmytro Shytikov and Iryna Pishel, 22 July 2022, Rejuvenation Research.DOI: 10.1089/ rej.2022.0029.
A brand-new research study finds that young blood did not considerably enhance the life expectancy of old mice. However, old blood substantially reduced the lifespan of young mice.
In a new study, old and young mice were surgically signed up with such that they shared blood circulation for three months. According to the outcomes, the old mice did not considerably benefit in terms of lifespan. On the other hand, the young mice that were exposed to blood from old animals had substantially decreased life expectancy compared to mice that shared blood with other young mice. The study was published on July 22 in the peer-reviewed journal Rejuvenation Research.

Heterochronic parabiosis is a research tool that is used to assess the result of organs and of blood-borne elements on old and young animals. Less controlled than direct blood exchange, parabiosis is a design of blood sharing between two surgically connected animals. Iryna Pishel, from Kyiv National Taras Shevchenko University and Bienta Ltd, in Kyiv, Ukraine, and coauthors used heterochronic parabiosis in between old and young mice and the isochronic controls for three months. Then they disconnected the animals and studied the effects of being signed up with on the blood plasma and animal lifespan.
” The most robust and interesting outcome of this study is the truth of a significant reduction in the life expectancy of young mice from heterochronic parabiotic pairs,” state the detectives. “These information support our assumption that old blood includes factors efficient in inducing aging in young animals. Finding and selective suppression of aging aspect production in the organism could be the key research field for life extension,” they conclude.
