TOKYO (AFP) Japanese researchers said Thursday they had created functioning human brain tissues from stem cells, a world first that has raised new hopes for the treatment of disease.
Stem cells taken from human embryos have been used to form tissues of the cerebral cortex, the supreme control tower of the brain, according to researchers at the government-backed research institute Riken.
The tissues self-organised into four distinct zones very similar to the structure seen in human foetuses, and conducted neuro-activity such as transmitting electrical signals, the institute said.
Research on stem cells is seen as having the potential to save lives by helping to find cures for diseases such as cancer and diabetes or to replace damaged cells, tissues and organs.
The team's previous studies showed stem cells differentiated into distinct cells but until now they had never organised into functioning tissues.
"In regenerative therapy, only a limited number of diseases can be cured with simple cell transplants. Transplanting tissues could raise hopes for greater functional recovery," the institute said in a statement.
"Cultivated tissues are still insufficient and too small to be used to treat stroke patients. But study of in-vitro cultivation of more mature cortex tissues, such as those with six zones like in the adult human brain, will be stepped up," it said.
The tissues could also serve as "a mini organ" for use in studying the cause of the Alzheimer's disease and developing vaccines, it said.
Embryonic stem cells are harvested by destroying a viable embryo, a process that some people find unacceptable.
Riken said cortex tissues were also obtained from "induced pluripotent stem cells," which are similar to embryonic stem cells but artificially induced, typically from adult cells such as skin cells.
The research was led by Yoshiki Sasai at Riken Centre for Development Biology in western Japan's Kobe.
The cultivated tissues look like minature mushrooms two millimetres (0.08 inches) in diametre.
The team also succeeded in making cortex tissues from the embryonic stem cells of mice.
Using mouse tissues, scientists confirmed they had formed a network of neurons that properly respond to stimulus.
The tissues can also be selectively induced to different cortex types controlling memories, visual sensation and other tasks.
The findings of the study were published in the November 6 online journal Cell Stem Cell in the United States.

Why not maybe theyd reconstruct her a brain

i dunno

in theory its a good idea to make brain cells, but for the religious people out there

its like playing God, but i see the benefits such as curing some brain diseases

as long as we can understand the full effects and consequences of it, im all for it

Serious issues in general chat... How quaint. I think that if they can refine the art perhaps my dad has a fighting chance to live a longer life. I don't agree with the fact that this may eventually lead to human cloning but for selfish reasons aforementioned I think its time we take a leap forward in this fight against diseases.

I just hope they're not using humans as lab rats. eeesh. That would be a mess.

there's been serious issues in gen chat


human cloning is already possible, as has turning stem cells into anything you want to turn it into

they already cloned a mouse which died 16 years ago jus the other day. Human cloning is possible but jus immoral.

Did it die 16 years ago, or just the other day?

it died 16 years ago.

and the clone was born the other day.

they should clone people...i want a clone...thatd be pretty sweet


and stem cell research would help MILLIONS of people but republicans care about a non-existant being they think they can contact telepathically knowing it will never respond more
