Regulation of gene expression during the ontogeny of haematopoiesis in the human fetal bone marrow is poorly understood. Studies in mice demonstrated that GATA-1, -2 and -3 play pivotal roles in haematopoiesis. In this study, we identified GATA-1-, GATA-2- and GATA-3-expressing cells in bone marrow sections and analysed the expression of GATA-transcription factors during the development of human fetal bone marrow haematopoiesis using semiquantitative reverse transcription-polymerase chain reaction (RT-PCR). We showed that GATA-1, -2 and -3 were expressed only in haematopoietic cells in the bone marrow. RT-PCR analysis demonstrated that (1) GATA-1 expression significantly increased during gestation; (2) GATA-2 expression peaked at the onset of medullary haematopoiesis, declined thereafter, and remained at a constant level after 30 weeks post conception; and (3) GATA-3 expression revealed no changes during development. The results indicated that the onset of medullary haematopoiesis in humans is accompanied by high expression of GATA-2, reflecting high proliferation rates of early haematopoietic progenitor cells, whereas expression of GATA-1 mirrors haematopoietic activity.
