Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye—called the ...

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 ...

Every year, millions of lives are suddenly, swiftly transformed by a stroke, which occurs when a blood vessel traveling towards the brain becomes obstructed, causing neurons to die off. Strokes are ...

For the first time, scientists have grown functional, brain-like tissue without using any animal-derived materials or added biological coatings. The development opens the door to more controlled and ...

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 ...

The federal government is looking for researchers who can, in 5 years, develop stem cell treatments to repair brain damage caused by stroke, neurodegeneration, and trauma. The Functional Repair of ...

Researchers have made great strides to understand early signs of autism. Studies have found that certain factors like genetics, sleep deprivation, excess fluid in the brain-and brain size-can increase ...

Stem cells persist in the adult mammalian brain and generate new neurons throughout life. A research group at the Biozentrum of the University of Basel reports in the current issue of "Science" that ...

Gut support cells communicate with surprising precision – like brain neurons – using tiny extensions to send instructions to the stem cells responsible for maintaining and healing the intestine. The ...
