The achievement will help to better investigate the various diseases associated with motor neurons.
Scientists have managed to grow miniature human brain with attached spinal cord and muscle tissue in laboratory conditions. And it can accelerate studies of various severe diseases. Grey pea the size of a lentil, which consists of brain cells, spontaneously began to produce such antennae on the end for connection with the spinal cord and the muscles, sends unian.net.
As The Guardian reports, after a connection is established, the researchers observed the reduction of muscle tissue under the control of the so-called brain organoid. The study is one of the last attempts of increasingly complex artificial reconstruction of the human brain in the laboratory. And this time, it provided a connection with other components of the Central nervous system .
Madeline Lancaster, who headed the research at the Laboratory of molecular biology medical research Council in Cambridge, explained: “We like to think of this as a mini-brain on the go”. The researchers used a new method of growing a miniature human brain from stem cells, which allows organoid to achieve a more advanced stage of development than during experiments in the past.
Latest artificial brain in the measurement of the number of neurons is close to that observed in the fetus at 12-16 weeks of pregnancy. However, the researchers emphasize that this structure is still too small and primitive to have any thoughts, feelings or consciousness.
