In nine of 19 patients the granulocytes showed a decrease in myeloid or an increase in monocyte antigen expression or both. In 11 of 19 patients the monocytes showed a decreased expression of monocyte antigens or an increase in myeloid antigens or both. The data suggest that in the myelodysplastic syndromes the granulocyte-macrophage progenitors do not develop along two divergent lines but differentiate with the emergence of dual characteristics.
