Scientists create mice with half-human brain

Scientists have successfully implanted human brain tissues into a tiny rodent, making the experiment a first of its kind.

Advances in science have led the scientists from a research institute ‘Salk Institute in California’ to inject part of human brain in a rodent brain, resulting in the creation of half-human and half-rodent brain. Since the experiment, the mice are alive and developing for months.

The study published in a scientific journal Nature Biotechnology suggested that researchers grafted human cerebral organoids and planted them into mouse brains while the host brain was supplying enough blood and oxygen to keep them alive. Organoids are tiny tissue cultures that are gotten from stem cells. The human brain cells not only survived, but also outnumbered the hosts’ brain cells.

Scientists involved in the study hope that this will help us in studying how the human brain develops and treat different disorders. “We expect the experimental system presented here to serve as a useful tool for a number of biomedical applications,” the study read.

Researchers proposed that this scientific breakthrough could even someday help in transplanting healthy human brains cells to replace dysfunctional or damaged tissues, reported The Sun.
