Function of alpha granules in platelets
Webfrom granules called "alpha" and "dense" granules. Alpha granules release additional vWf and platelet derived growth factors (PDGF). vWF assists with further platelet adherence and activation. PDGF facilitates a variety of functions that assist in the long-term wound healing of tissue damage. Dense granules release adenosine diphosphate (ADP).
