“…They contain mitochondria, mRNA, and all the translational machinery needed for protein synthesis (approximately 5000 different proteins are present inside platelets 7 ), including the ribosomes, endoplasmic reticulum, and Golgi apparatus. They host several types of storage granules containing a wide array of potentially active molecules (fibrinogen, growth factors, cytokines, chemokines, adenosine diphosphate [ADP], and serotonin), 8 and they secrete a myriad of membrane vesicles (both exosomes and microvesicles) into the blood that together represent the majority of circulating vesicles 9 . Moreover, platelets have adhesion and immune receptors 10,11 .…”
