Jerry jones: i have the brain of a 40 year old man

Jerry Jones will outlive us all.

This always has been a working theory around these parts, admittedly rooted in a gut feeling rather than tangible medical evidence.

But now ... now we have something to work off. The Dallas Cowboys owner received some very unusual news during a recent visit to the doctor. He shared said unusual news with the media, because, well, that's what makes Jerrah, Jerrah.

"I've been told that I have, by CT Scans, that it's like the brain of a 40-year-old," Jones said, according to The Dallas Morning News. " ... The guy really did not know it was me. I was there anonymously. He said, 'And so I just wanted to come down. I saw your chart. I know how old you are. That part is really impressive.' "

(We like to imagine the doctor racing out of surgery so he can steal a glance of The Anonymous Brain.)

Let's do some math. Jones is 70. His brain -- as we now know thanks to science -- is 40. Extrapolating that data (and assuming proper conditioning and technology keeps the rest of his body in working order), we can safely approximate Jones having a 146-year lifespan.

Of course, that's not factoring in the chance Jerry Jones' brain has gone Benjamin Button. In which case, all bets are off.

Jerry  might soon get the chance to trade in his 40 year old brain for a newer model.  They're growing brains in laboratories these days.

 

Go get yours, Jerry!

 

Mini human brains grown from stem cells

A cross section of an entire organoid shows the development of different brain regions. All cells are in blue, neural stem cells are in red, and neurons are shown in green.

 

The first complete living model of the developing human brain has been created in a lab dish.

 

Researchers grew human stem cells in an environment that encouraged them to form pea-size gobs of brain tissue, which developed into distinct brain tissues, including a cerebral cortex and retina.

 

The minibrains were used to model microcephaly, a human genetic disorder in which brain size is dramatically reduced. Though not capable of consciousness or other higher cognitive functions, the minibrains allow scientists to study aspects of the developing human brain that are difficult to model in animals. 

 

"The mouse brain is not always a good model system for the human brain," study researcher Jüergen Knoblich, of the Austrian Academy of Science's Institute of Molecular Biotechnology in Vienna, said at a news conference. "Our system allows us to study human-specific features of brain development."

 

Other groups have grown small pieces of neural tissue in the lab before, but none has been able to successfully grow tissue that contained both a cortex — the specialized outer layer of the brain — and other brain regions, Knoblich said.

 

Started with stem cells
To create the minibrains, Knoblich and his team took human embryonic stem cells or induced pluripotent stem cells — both types of cells with a capacity to develop into any kind of tissue — and grew the cells in conditions that allowed them to form a tissue called neuroectoderm, which develops into the nervous system. The researchers embedded fragments of the tissue in droplets of gel to create a scaffold to guide further growth. They then transferred the droplets to a spinning bioreactor that increased nutrient absorption.

 

After 15 to 20 days, the tissue formed minibrains called cerebral organoids, each enclosing a fluid-filled region, much like the cerebral ventricles that contain cerebrospinal fluid in the human brain. After 20 to 30 days, some of the organoids formed defined brain areas, including a cerebral cortex (the brain's complex outer layer); retinal tissue, the light-sensitive part of the eye; meninges, the membranes that envelope the brain; and choroid plexus, which produces the cerebrospinal fluid that bathes the brain.

The minibrains grew 2 to 3 millimeters (0.08-0.1 in) in diameter, and have survived in lab dishes for 10 months so far. Their size is limited, because they lack a circulatory system to provide nutrients and oxygen to their core regions. As a result, the brains could not develop the many layers seen in a real human brain, the researchers said.

 

Learning about disorders
In addition to modeling how a healthy human brain develops, the organoids can be used to model brain disorders. Knoblich and his colleagues used their minibrains to study microcephaly, a disorder not easily studied in mice because their brains are already smaller than human ones. They took skin cells from a microcephaly patient and reprogrammed them into stem cells, which they then grew into brain organoids.

 

The mini microcephaly brains grown from the patient's cells were smaller than ones grown from normal tissue, but had more neuron growth. The results suggest the brains of microcephaly patients develop neurons too early, before their brains have grown large enough. Other experiments showed the orientation in which the stem cells divide could also play a role in the disorder.

 

Biologist Gong Chen of Pennsylvania State University, who was not involved with the research, called it "a remarkable achievement," adding, "it opens the door for many studies on the human brain using human neurons."

 

This method of growing minibrains in a lab could be used to or test medications, or to study other brain disorders. "Ultimately, we would like to move to more common disorders, like schizophrenia and autism," Knoblich said, though he added that it's premature to speculate when scientists will develop minibrains complex enough to do so. 

 

The research was detailed online Wednesday in the journal Nature. 

This article has been updated to note where the study was published, and to correct Gong Chen's academic affiliation.
