Platelet structure

<p>Platelets have multiple surface receptors, a cannalicular system, microtubules, mitochondria, three types of granules (lysosomal, alpha, and dense), and deposits of small factors like glycogen (<a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0002858#pntd-0002858-g002" target="_blank">Figure 2</a> and <a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0002858#pntd-0002858-g003" target="_blank">3</a>) <a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0002858#pntd.0002858-George1" target="_blank">[54]</a>. Whereas dense granules contain factors that potentiate platelet activation, α-granules contain growth factors and clotting proteins that contribute to hemostasis <a href="http://www.plosntds.org/article/info:doi/10.1371/journal.pntd.0002858#pntd.0002858-Blair2" target="_blank">[130]</a>.</p
