Web9 nov. 2024 · In humans, 150–450 billion platelets circulate per liter of blood, with a life span of 8–10 days, requiring a daily turnover of 100 billion platelets (70 million/min) to maintain a physiological platelet concentration. Platelets originate from megakaryocytes (MKs), large cells described for the first time in 1890 by Howell and Donahue ( 1) . Web22 apr. 2024 · In contrast to the erythrocyte, which has a diameter of 7 to 8 microns and a volume of 85 to 100 fL, megakaryocytes have an average diameter of 20 to 25 microns and a volume of 4700 ± 100 fL ( picture 2 ) [ 6 ]. Some of the largest megakaryocytes have diameters of 50 to 60 microns and volumes of 65,000 to 100,000 fL.
