[Differentiation of human megakaryocytes in culture starting from the primordial circulating cells in the newborn]. 1978

W Vainchenker, and J Guichard, and J Breton-Gorius

Human neonatal blood mononuclear cells were seeded in plasma clot containing high dose of a crude erythropietin. Pure megakaryocyte colonies were observed rarely and most of the colonies were mixed, megakaryocytes being located between subcolonies of erythrocytic bursts. The megakaryocytic nature of large cells could be clearly confirmed by the presence of platelet peroxidase, demarcation membranes, and alpha granules detected by electron microscopy; in addition mature micromegakaryocytes were recognized, shedding platelets.
