abstract

  • During pregnancy, nucleated fetal erythrocytes enter the maternal circulation and can be isolated efficiently from the maternal cells by multiparameter flow cytometry. Male DNA, implying presence of a male fetus, can be identified in flowsorted maternal blood by polymerase chain reaction with oligonucleotide primers flanking single-copy Y-specific DNA sequences. Among flow-sorted samples, we correctly identified fetal sex in 17/18 (94%) pregnancies of 10-21 weeks gestation. Maternal blood thus provides a potential opportunity for prenatal diagnosis that could preclude the need for invasive procedures in current use. © 1991 Oxford University Press.
