Japanese researchers said Thursday they had created functioning human brain tissues from stem cells, a world first that has raised new hopes for the treatment of disease. Stem cells taken from human embryos have been used to form tissues of the cerebral cortex, the supreme control tower of the brain, according to researchers at the government-backed research institute Riken.
The research was led by Yoshiki Sasai at Riken Center for Development Biology in Kobe.
The tissues self-organized into four distinct zones very similar to the structure seen in human fetuses, and conducted neuro-activity such as transmitting electrical signals, the institute said.
Research on stem cells is seen as having the potential to save lives by helping to find cures for diseases such as cancer and diabetes or to replace damaged cells, tissues and organs.
