Scientists transplanted into the mouse’s head a tiny human brain

Scientists of the Institute of Biological Research Salka implanted in the head of the mouse “mini-brain” rights. Transplanted nerve cells not only took root, but began to develop. The behavior of the experimental rodents did not change at all.

Biologists managed to grow cells of the human brain in the laboratory. New formations were transplanted into the mouse’s head, where they could live and grow neurons. Scientists were able to create cerebral organoids, through which you can study schizophrenia.

The same technology researchers plan to use to treat brain damage in humans. But first they have to study the organ more thoroughly and find out at what stage of its development deformations or mutations appear. Earlier scientists of the Salk Institute had already conducted such experiments, but implanted tiny brains died five days later without oxygen and nutrients. This time samples in 80% took root in the head of a mouse and about three months developed normally. After the first neurons appeared, the brain could live another 233 days. Eventually the organ resembled the brain of a newborn baby.
