  • These studies were designed to quantitate and determine the DNA content distribution of human marrow megakaryocytes using whole bone marrow. Cellular DNA content within megakaryocytic cells was established by measuring propidium iodide staining in marrow cells expressing platelet glycoprotein IIb/IIIa (Gp IIb/IIIa). These studies were based on the development of a method for rapid analysis of whole marrow cell preparations by a dual fluorescent system. DNA values ranging from 2 to 64 C were observed in all samples tested, with 16 C corresponding to the modal ploidy class representing almost one-half of the cells containing Gp IIb/IIIa. The second most frequent ploidy class corresponded to 32 C, followed by 8 C, with 20% and 15%, respectively. Virtually all high-ploidy megakaryocytes (greater than or equal to 8 C) were of low density (less than 1.050 g/cm3), whereas 2 and 4 C megakaryocytes were evenly distributed between less than or equal to 1.050 and greater than 1.050 g/cm3 marrow cells. These studies conclusively establish DNA content distribution of normal human marrow megakaryocytes and provide a basis for the study of states of altered megakaryocytopoiesis.
