Study: Blood From Children ‘Rejuvenates’ Older Bodies And Brains

Study finds blood from young people to have a 'rejuvenating' effect on older bodies and brains

Scientists have found that blood taken from young people has a “rejuvenating” effect on older bodies and brains when injected. 

The blood plasma taken from a group of young volunteers was found to improve the memory, cognition, and physical activity of mice in a recent study conducted by Sakura Minami of Alkahest, the company behind the study. reports:

Previous research has found that stitching old and young mice together has an interesting effect. While sharing a blood system works out well for the older mouse, the younger one isn’t so lucky. The young animals started to show signs of brain ageing, while the brains of the older mice started to look younger. “We see a rejuvenation effect,” says Minami.

The key to youth appears to be in the blood plasma – the liquid part of blood. Several studies have found that injecting plasma from young mice into old mice can help rejuvenate the brain and other organs, including the liver, heart, and muscle.

Could blood plasma from young people have the same benefits? To find out, Minami and her colleagues took blood samples from 18-year-olds, and injected them into 12-month-old mice. At this age, the equivalent of around age 50 for people, the mice start to show signs of ageing – they move more slowly, and perform badly on memory tests.

The mice were given twice-weekly injections of the human plasma. After three weeks of injections, they were submitted to a range of tests. The treated mice’s performance was compared to young, 3-month-old mice, as well as old mice who had not received injections.

New neurons

They found that human plasma does have the power to rejuvenate. Treated mice ran around an open space like young mice. Their memories also seemed to improve, and they were much better at remembering their way around a maze than untreated mice.

“Young human plasma improves cognition,” says Minami, who presented her findings at the Society for Neuroscience annual meeting in San Diego, California, on Monday. “Their memory was preserved.”

“It’s more or less what we would expect,” says Victoria Bolotina, at Boston University in Massachusetts. “The blood of young people must have something in it that’s important for keeping them young,” she says.

The team then examined the brains of the treated and untreated mice. They looked for clues on the birth of new neurons in the hippocampus – a process called neurogenesis, which is thought to be important for memory and learning. Sure enough, the treated mice appeared to have created more new cells in their brain. “Young human plasma treatment can increase neurogenesis,” says Minami.

Minami says she has identified some factors in young blood that might be responsible for these benefits, but that she won’t reveal what they are yet. Some of them seem to be crossing into the brain, while others may be acting remotely, elsewhere in the body, she says.

She hopes to one day translate the findings into an anti-ageing treatment for people – one that might help those who start to experience the effects of an ageing brain. “There’s anecdotal evidence that people experience benefits after blood transfusions,” she says.

The company she works for, Alkahest, has already started a trial of young blood in people with Alzheimer’s disease.

    • This is a fake news site. Man, religious people are so gullible. You really will believe anything.

        • Haha, okay. Way to not respond to the fact that you’ve just been duped by a blatantly fake news site. And think about it….if you’re that gullible, what else have you been duped by? Just saying. 😉

          • Do you want me to defend a site?
            Do you want me to defend the existence of the Creator ?
            Do you want me to defend your right of being only COSMIC DUST?

          • Et je vis un ange qui se tenait dans le soleil. Et il cria d’une
            voix forte, disant à tous les oiseaux qui volaient par le milieu du
            ciel: Venez, rassemblez-vous pour le grand festin de Dieu,

            afin de manger la chair des rois, la chair des chefs militaires, la
            chair des puissants, la chair des chevaux et de ceux qui les montent, la
            chair de tous, libres et esclaves, petits et grands.

          • LMFAO. Sorry dude, but quoting the Bible in French doesn’t make you look any less idiotic. Work on your critical thinking, that might help.

          • И цари земные, и вельможи, и богатые, и тысяченачальники, и сильные, и всякий раб, и всякий свободный скрылись в пещеры и в ущелья гор,
            и говорят горам и камням: падите на нас и сокройте нас от лица Сидящего на престолеи от гнева Агнца;
            ибо пришел великий день гнева Его, и кто может устоять?

          • Lol, copying and pasting the Bible in Russian doesn’t make you smart, either. Look, I can copy and paste shit in different languages too!

            Here’s a Biblical verse in Amuzgo Guerrero:
            Luaa ñˈoom na matseijndaaˈñenaˈ tsjaaⁿ nnˈaⁿ na tuiiñe Jesucristo, na wjaacˈoomnaˈ David ñequio Abraham na jndyowicantyjooˈ joona na tueˈcañoomnaˈ jom.

            And Arabic:
            1 فِي البَدءِ خَلَقَ اللهُ السَّماواتِ وَالأرْضَ. 2 كانَتِ الأرْضُ قاحِلَةً وَفارِغَةً. [a] وَكانَ الظَّلامُ يَلُفُّ المُحِيطَ، وَرُوحُ اللهِ تُحَوِّمُ [b] فَوقَ المِياهِ. 3 فِي ذَلِكَ الوَقتِ، قالَ اللهُ: «لِيَكُنْ نُورٌ.» فَصَارَ نُورٌ. 4 وَرَأى اللهُ أنَّ النُّورَ حَسَنٌ. ثُمَّ فَصَلَ اللهُ النُّورَ عَنِ الظَّلامِ. 5 وَسَمَّى النُّورَ «نَهاراً» وَسَمَّى الظَّلامَ «لَيلاً.»


            ਪਰਮੇਸ਼ੁਰ ਨੇ ਅਕਾਸ਼ ਤੇ ਧਰਤੀ ਨੂੰ ਸਾਜਿਆ। 2 ਪਹਿਲਾਂ ਧਰਤੀ ਬਿਲਕੁਲ ਸੱਖਣੀ ਸੀ; ਧਰਤੀ ਉੱਤੇ ਕੁਝ ਵੀ ਨਹੀਂ ਸੀ। ਹਨੇਰੇ ਨੇ ਸਮੁੰਦਰ ਨੂੰ ਕੱਜਿਆ ਹੋਇਆ ਸੀ, ਅਤੇ ਪਰਮੇਸ਼ੁਰ ਦਾ ਆਤਮਾ ਪਾਣੀ ਉੱਤੇ ਚੱਲਦਾ ਸੀ।

            And Czech:
            Na počátku Bůh stvořil nebe a zemi. 2 Země pak byla pustá a prázdná, nad propastí byla tma a nad vodami se vznášel Boží Duch.

            Here’s one in German:
            Am Anfang schuf Gott Himmel und Erde. 2 Noch war die Erde leer und ungestaltet, von tiefen Fluten bedeckt. Finsternis herrschte, aber über dem Wasser schwebte der Geist Gottes.

            And Korean:
            태초에 하나님이 [a]우주를 창조하셨다.

            This took me all of 30 seconds. Copying and pasting shit does not make you smart, even if you copy and paste shit written in different languages. A two year old can do it. Intelligence, critical thinking, rationality, knowledge, and the use of logic make a person smart. You lack all all of these things. Try working on that, instead of thinking that you’re smart because you know how to copy and paste. LMFAO. You can’t make this shit up.

          • C’est le meilleur que je peux faire pour un ver qui réponde une conversation au bout de 8 mois.

          • Okay, first of all, your French sucks. Why write in French if you can’t do it properly? Secondly, a worm? Is that really your best insult? Again, you’re showing your lack of critical thinking. Lastly, I was replying to your comment from 2 months ago, not 8 months ago. Your comment from 8 months ago was nonsensical and not even worth replying to. Your comment from 2 months ago wasn’t really worth replying to either, but since someone else joined the conversation, I thought I would point out how completely ridiculous your reply was, even though I’m sure it’s already apparent to anyone reading this.

            And bravo at changing the subject and deflecting from your own ridiculousness – again. At least we know there’s one thing you’re good at. Maybe next time, try actually responding with something intelligent. If you’re able to, that is. You want to get away from religion, my friend. It’s frying your brain.
