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 ...

Brain stem gliomas very rare growths that begin in the glial cells of the brain stem. Doctors can diagnose brain stem glioma using neurological exams and scans. Treatment may involve chemotherapy, ...

Aging affects all of us and leads to cell and tissue loss of function, multiple diseases, and eventually death. And, even after decades of robust research and billions of dollars spent, there are only ...

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 ...

Researchers have created model embryos from mouse stem cells that form a brain, a beating heart, and the foundations of all the other organs of the body -- a new avenue for recreating the first stages ...
