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 ...

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 ...
