Japanese researchers
make brain tissues from stem cells
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.
The Good News
Well, let’s count the possible applications here:
1. Treatment for brain damage sustained via disease or trauma. The conventional
wisdom has always been that recovery from brain damage requires building new
connections and otherwise working around damage that has to be taken as a permanent
fact of life. If we can grow new brain tissue, this is no longer the case.
2. Treatment for degenerative disease. There are a number of very exciting
possible treatments being developed for diseases such as Parkinsons
and Alzheimers.
The ability to produce vital new brain tissue can only be a boon to fighting
these diseases.
3. Life Extension. If we’re going to live longer, it’s a cinch that
we’re going to need longer-lasting brains. This technology can help make that
possible.
4. Performance Enhancement. Growing new brain tissue might be more than
a way of keeping youthful mental stamina and performance well into our senior
years; perhaps it would enable us to augment and upgrade our brain performance
at any age.
Live to see it!
