How and where are platelets produced
Megakaryocyte and platelet production is regulated by thrombopoietin, a hormone produced in the kidneys and liver. Each megakaryocyte produces between 1,000 and 3,000 platelets during its lifetime. An average of 10 11 platelets are produced daily in a healthy adult.
