Isolating Fetal Cells From Maternal Blood: Advances in Prenatal Diagnosis Through Molecular Technology

Simpson, Joe Leigh·1993·JAMA

Abstract

Objectives To review the rationale for and progress toward the goal of isolating and analyzing fetal cells circulating in maternal blood, and to explore the feasibility of this method in providing noninvasive prenatal cytogenetic diagnosis.Data sources Critical review of data published since the first report (1969) of fetal metaphases in maternal blood. Emphasis is placed on data since the demonstration by polymerase chain reaction (PCR) in 1989 and 1990 that fetal cells indeed exist in maternal blood.Data synthesis Clinical evaluations have not yet been conducted, but it is already clear that molecular technologies have allowed the unequivocal demonstration of fetal cells in maternal blood. Using PCR, our own group and others have demonstrated Y sequences and single gene sequences (eg, hemoglobin LeporeBoston) in maternal blood. Thus, fetal DNA sequences indeed exist in maternal blood. Among the various candidate cells, the most promising appear to be fetal nucleated red blood cells. We isolated nucleated red blood cells on the basis of flow-sorting for the transferrin receptor and glycophorin-A. Enriched samples were then subjected to fluorescence in situ hybridization with chromosome-specific probes. This approach allowed us to detect trisomy 21 and trisomy 18, work later confirmed by others.Conclusions Isolating and analyzing fetal cells from maternal blood is clearly possible. Several key biologic questions remain--the optimal cells for isolation, frequency of cells in maternal blood, timing during gestation for maternal blood sampling, and the likelihood of persistence of fetal cells after delivery. Clinical evaluations planned by the National Institute of Child Health and Human Development will determine the sensitivity and specificity of this method and its precise role in prenatal cytogenetic diagnosis.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cell-free fetal DNA disappears from the maternal circulation shortly after delivery and therefore does not confound prenatal genetic investigations in subsequent pregnancies.

    “Unlike fetal cells, it disappears from the maternal circulation shortly after delivery (319,320) and therefore does not confound prenatal genetic investigations in subsequent pregnancies (321,322).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
