In the fetal liver, megakaryocytes were wholly located among growing fetal liver cells and near foci of hemopoiesis. Some megakaryocytes in the fetal liver were small7890- lymphoid-like megakaryocytes. The size of megakaryocytes both in the fetal liver (14.79 ± 4.52μm) and in the fetal bone marrow (16.08±7.39 μm) was small, which did not vary significantly over the gestation age ranging from 3 to 6 or 7 months. However, the maturation stage of megakaryocytes in the fetal liver shifted to more mature stage with the advancement of gestation, although the maturation stage of megakaryocytes in the fetal bone marrow did not change with the advancement of gestation from 4 to 7 months, the megakaryocyte in the fetal bone marrow was less mature展开更多
