Platelet-derived EVs procoagulant and prothrombotic effects.

Molecule Mechanism References
Phosphatidylserine surface expression Negative charged surface creates binding sites for factors II, Va, Xa (prothrombinase complex) (112)
Tissue Factor surface expression It binds factor VIIa on phosphatidylserine- containing surface and activates extrinsic pathway of coagulation (113)
