Antimaturation factor (platelet factor 4 or active peptide segments thereof) is employed in the clinical treatment of coagulation disorders as an anticoagulant operating via an autoregulator mechanism for selectively suppressing megakaryocytopoiesis. Exposure of immature megakaryocytes to antimaturation factor reversibly inhibits cell maturation and, accordingly, functions characteristic of the mature cell, including platelet production and expression of genes coding for platelet coagulation factors, are reversibly suppressed.
