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 ...

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 ...

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

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 ...

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 ...

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 ...

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 ...

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 ...
