Cell fragments called platelets are essential to promote blood clotting. Researchers have now discovered novel molecular interactions at the surface of platelets that control blood clotting. Cell ...

Researchers have developed synthetic platelets from biodegradable polymers. In animal models, the synthetics attach to natural platelets and stem bleeding faster than current treatments. Blood loss is ...

Platelets are probably best known for their role in blood clotting, making scabs and related, if less salubrious, contributions to heart attacks and strokes. But these tiny, saucer-shaped blood cells ...

Platelets, the tiny cell fragments whose job it is to stop bleeding, are very simple. They don't have a cell nucleus. But they can "feel" the physical environment around them, researchers at Emory and ...

Platelets are specialized blood cells that participate in the clotting process the body uses to stanch bleeding. A team of researchers at Georgia Tech led by chemist L. Andrew Lyon and biomedical ...

Platelets are cells in the blood whose job is to stop bleeding by sticking together to form clots and plug up a wound. Now, for the first time, scientists have measured and mapped the key molecular ...

Heart disease, stroke, sepsis and cancer are incredibly serious conditions which together cause the greatest number of deaths around the world. They're unique illnesses, but they have something in ...

As people age they become more prone to blood clotting diseases, which can be caused when blood platelets clump together. This clumping can lead to strokes and cardiovascular disease. For decades, ...

COVID-19 triggered changes in blood platelets could be a contributing factor to the onset of heart attacks and strokes in some patients with the disease, new research reveals. Scientists from the ...

A new discovery from the University of Virginia School of Medicine could let doctors ramp up production of blood-clotting platelets on demand, a timely finding following the Red Cross' declaration ...

Blood clotting is one of the most critical, protective processes in human physiology. When something goes wrong with clotting — either because there is too much clotting, leading to a stroke, or not ...
