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 ...

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 ...

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, ...

Every 40 seconds, someone in the United States has a stroke. For survivors of the most common type of stroke, called an ischemic stroke, only about 5 percent fully recover. Most others suffer from ...

Neurons from grafted stem cells contain intrinsic codes for navigating and forming connections, which may improve cell therapy for a brain short-circuited by stroke. Some parts of our bodies bounce ...

A team of scientists—including Agnieszka Ciesielska (left), Barbara Klein (center), and Jeanne Paz (right)—showed that modified stem cells can improve brain activity, even when administered more than ...

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 ...

Here is some background information about stem cells. Scientists believe that stem cell research can be used to treat medical conditions including Parkinson's disease, spinal cord injury, stroke, ...
