Background Rheumatoid arthritis (RA) is associated with inflammation-driven hypercoagulability and increased venous ...

When skin is cut or damaged, tiny cell fragments circulating in the blood, called platelets, arrive at the injury and spread out to stop the blood from leaking out. Once enough layers of platelets ...

Megakaryocytes, which are derived from hematopoietic stem cell precursors in bone marrow, form and release platelets; these circulate in the blood for 8 to 10 days before they are removed by hepatic ...

Researchers have discovered a distinct, secondary population of platelets that appears with aging and have hyperreactive behavior and unique molecular properties, which could make them easier to ...

A new study created a score to identify patients with platelet hyperreactivity and risk of related, future cardiovascular disease. Platelets are circulating cell fragments known to clump up and form ...

An unhealthy lifestyle, diseases or injuries, genetic predisposition, and increased coagulation tendency can promote the formation of thrombi in blood vessels. These clots obstruct the flow of blood ...

When a vascular injury occurs, platelets in young mice form much smaller blood clots (left) than platelets in old mice (right), where the clot almost blocks the blood vessel. Fluorescence microscopy ...
