We are interested in the regulation of the tissue specificity of the megakaryocyte-specific platelet glycoprotein IIb gene. The murine embryonic stem (ES) cells are able to differentiate into erythroid, mast and granulomonocytic cells in appropriate culture conditions. Our goal is to optimize the production of myeloid cells including megakaryocytes (MKs) by ES cells. We have found that coculture with MS-5 stromal cells and the presence of a cocktail of hematopoietic growth factors (HGFs) [stem cell factor, interleukin 3 (IL-3), IL-6, IL-11, G-CSF and erythropoietin] had a high synergistic activity on differentiation of ES cells into pure and MK-containing myeloid colonies from day 12 embryoid bodies. Thrombopoietin increased the number of MKs only when added to the HGF cocktail in the presence of MS-5 cells. Interestingly, many MKs exhibited a "hairy" appearance evocative of pseudopodial proplatelet formation. Expression of genes specific for the megakaryocytic lineage, GPIIb, PF4, mpl and GPIIIa, was detected by reverse transcriptase-polymerase chain reaction (RT-PCR) during differentiation of ES cells, and their relative time course was evaluated. This demonstrates that optimized culture conditions for the differentiation of ES cells into the MK lineage provide a useful tool for the study of the regulation of expression of genes during megakaryocytopoiesis.
