Abstract

In the present study, we tried to detect nucleated erythrocytes in maternal blood by means of the HAE9 antibody that binds to the antigen of erythroblasts (Ag-Eb) on nucleated erythroid cells. Umbilical cord blood and placental cells, which are known to contain a high number of nucleated erythrocytes, indeed demonstrated a high percentage of Ag-Eb-positive cells. In comparison, HAE9 stained up to 4.5% of the peripheral blood cells collected from pregnant women, but not those of nonpregnant women or normal men. These results, demonstrating a simple and reliable method for the identification of nucleated erythrocytes in the maternal circulation using the anti-Ag-Eb antibody, might open new possibilities for the detection of nucleated erythrocytes in maternal blood.
