Introduction to a review series on megakaryopoiesis and platelet production

Hematologists have long been fascinated by how platelet production occurs, and our understanding continues to evolve as technology advances and as more and more genetic causes for thrombocytopenia are discovered. In this Review Series on megakaryopoiesis and platelet production edited by Associate Editor John Crispino, experts in the field discuss the latest insights into megakaryopoiesis in fetal and adult life, the varied roles that megakaryocytes are now recognized to play, the mechanics of platelet creation, and how all of this new knowledge underpins clinical disorders requiring diagnosis and management.
