Scientists at Ohio State University, the United States has succeeded in developing a nearly complete human brain from stem cell tissue brain in the lab.
Professor Rene Anand, who presented the work at the Military Health System Research Symposium in Fort Lauderdale, Florida, says this artificial human brain is just about the size of a pencil eraser, which means it is like the brain of 5-week-old fetus. However, it contains only 99% the genes of the "real version". To create this brain, the scientists spent about 15 weeks and they will have to wait 1-5 weeks more.
"If we let it go to 16 or 20 weeks that might complete it, filling in that 1 per cent of missing genes," said Professor Anand. "We don't know yet."
Identifiable structures of the lab-grown brain: the cerebral hemisphere, the optic stalk and the cephalic flexure
For the purpose of further research on diseases related to human nerve as Alzheimer or Parkinson, scientists have spent a lot of effort to create an artificial human brain to replace the mouse brain.
Experiments on mouse brain previously did not bring effectively real results about these diseases. An artificial brain will allow the testing of new drugs process more quickly and accurately than before when we did clinical examination for the genetic causes of symptoms caused disturbances central nervous system.
“If you have an inherited disease, for example, you could give us a sample of skin cells, we could make a brain and then ask what’s going on,” Anand added. “We can look at the expression of every gene in the human genome at every step of the development process and see how they change with different toxins. Maybe then we’ll be able to say ‘holy cow, this one isn't good for you.’”
