Mechanics and contraction dynamics of single platelets and implications for clot stiffening
2011
Blood platelets aggregate to form clots that prevent haemorrhage. Knowledge of single-platelet mechanics is scarce, however. Atomic force microscopy experiments now show that platelets contract rapidly on contact with fibrinogen, and adhere strongly to multiple fibrin polymers, enhancing the elasticity of clots. These findings are relevant to disorders of platelet function, such as thrombosis.
