WebOct 10, 2015 · Platelet clearance Several mechanisms mediate platelet clearance. One mechanism appears to function via aging (senescence) induced signals, ie, via glycan degradation and apoptotic mechanisms. Platelets are also removed by immune (antibody mediated) responses. Go to: Senescence-induced platelet clearance by the AMR WebMar 24, 2024 · This process is called hemostasis and involves two main components: First, blood platelets attach to the wound edges, form a plug and provisionally seal the injury. Secondly, blood coagulation or the coagulation cascade is initiated, leading to the formation of long fibrin fibers, which together with platelets seal the wound tightly.
