Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the ...

Brain damage caused by blocked blood vessels may be treatable using injections of stem cells, according to a new study by researchers from the University of Zurich and the University of Southern ...

The human brain can do many amazing things, but self-repair is not one of its repertoire of abilities. Once neurons die—from trauma, stroke, or disease—they rarely grow back. Scientists have been ...

When someone has a stroke—a leading worldwide cause of death and disability—time is of the essence. Almost nine out of 10 cases are ischemic strokes, caused by restricted blood flow in the brain, and ...

A group of Chinese researchers has created a robot with a brain made of human stem cells. The technology is technically a "brain-on-a-chip," and the researchers have been working to train the robot to ...

Clues to keeping the brain’s regenerative cells youthful and energetic into old age have emerged by applying CRISPR gene editing to mice 1. Age impedes the ability of the brain’s stem cells to churn ...

Stem cell transplantation can reverse stroke damage, researchers at the University of Zurich report. Its beneficial effects include regeneration of neurons and restoration of motor functions, marking ...

The brain stem is a portion of the brain made of four distinct sections: the diencephalon, mesencephalon, pons, and medulla oblongata. Each of these sections has associated functions which are vital ...

Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye—called the cornea—can heal from minor scratches within a single day. The brain is not one ...

Like the seeds of a forest, a few cells in embryos eventually sprout into an ecosystem of brain cells. Neurons get the most recognition for their computing power. But a host of other cells provides ...
