The brain from a test tube
American scientists have announced a grown copy of the human brain
Tape.RooScientists from the Ohio State University said that they managed to grow an almost complete copy of the human brain. A message about this appeared on the official website of the university (Scientist: Most complete human brain model to date is a ‘brain changer').
The head of the study, Professor Rene Anand, said that the sample grown by his team corresponds to the characteristics of the five-week-old embryo. It reproduces 99 percent of the genes present in the real brain, and all the main departments are represented, but there is no blood vessel system.
Anand did not provide a full report on the experiment, saying that it would appear after he received a patent for the technology. According to his assessment, this is the most accurate biological model of the brain to date. He noted that previous researchers were able to copy only certain aspects of the brain.
It took about 12 weeks to grow the model. It is based on adult skin cells that are reprogrammed into induced stem cells that can change the direction of their specialization and form any tissue in the body.
The researcher noted that sensory stimuli do not enter the model and the thought process does not go in it, which excludes possible ethical problems.
According to the scientist, the invention will be useful for studying the causes of various diseases of the nervous system and checking the effectiveness of medicines. Anand is the co-founder of the startup NeurXstem, dedicated to the commercialization of the method he invented for the production of copies of the brain.
