Fetal lymphocytes, trophoblasts, and nucleated red blood cells have each been separated from maternal blood by methods such as flow cytometry, magnetic cell sorting, and charge flow separation. The frequency of fetal cells among circulating maternal mononuclear cells remains to be ascertained. Current estimates range from about 10−5 to 10−7, but the numbers may be increased in women carrying aneuploid fetuses. Fetal cells separated from maternal blood have been studied by methods such as… 
Culture of fetal cells from maternal blood for prenatal diagnosis.
TLDR
Developing conditions which allow the number of fetal-derived cells to expand in culture and thenumber of maternally derived cells to be suppressed in culture may lead to a new selection process for obtaining fetal cells.
Isolation of fetal nucleated red blood cell from maternal blood using immunomagnetic beads for prenatal diagnosis.
TLDR
The immunomagnetic beads method for isolation of fetal nucleated red blood cells (FNRBCs) from peripheral blood of 78 pregnant women for prenatal diagnosis is simple and cost effective and may thus be applied for prenatal Diagnosis.
Noninvasive prenatal diagnosis.
Non-invasive prenatal diagnosis of aneuploidies: new technologies and clinical applications
TLDR
The most recent advances in methods for NIPD of aneuploidies, including next-generation sequencing and methylated DNA immunoprecipitation real-time quantitative PCR-based approaches are highlighted and their future implications in clinical practice are discussed.
Detection of gamma‐globin mRNA in fetal nucleated red blood cells by PNA fluorescence in situ hybridization
TLDR
The application of peptide nucleic acid (PNA) probes for tyramide amplified flow fluorescence in situ hybridization (FISH) detection of gamma‐globin mRNA in fixed fetal NRBC is investigated.
The Maternal–Foetal Interface and Gestational Chimerism: The Emerging Importance of Chimeric Bodies
TLDR
Findings of cellular transfer across the maternal/foetal interface raise questions about intermingling and permeability of human organism boundaries, and suggests that chimeric, permeable bodies are of increasing value as cellular therapeutic strategies gain in importance for human health.
Recent advances in prenatal screening and diagnosis of genetic disorders.
TLDR
The currently available prenatal and screening diagnostic tests for genetic disorders with a focus on the latest technology are discussed, the newest using recombinant deoxyribonucleic acid technology in the examination of fetal cells.
Microfluidic blood cell sorting: now and beyond.
TLDR
The conventional methods of processing and sorting blood cells are reviewed, followed by a discussion on how microfluidics is emerging as an efficient tool to rapidly change the field of blood cell sorting for blood-based therapeutic and diagnostic applications.
Types of Clinical Samples and Cellular Enrichment Strategies
TLDR
This chapter briefly discusses the types of clinical samples available, focusing primarily on the ones that contain cells, and discusses about the conventional technology currently used for cell enrichment.

Nucleated erythrocytes in maternal blood: quantity and quality of fetal cells in enriched populations.
TLDR
It was determined that less than one nucleated erythrocyte per ml of maternal blood was of fetal origin, suggesting that the fetal cells are less suitable for fluorescence in-situ hybridization (FISH) analysis than similar preparations from other sources.
Isolation of fetal DNA from nucleated erythrocytes in maternal blood.
TLDR
It is demonstrated that it is possible to isolate fetal gene sequences from cells in maternal blood by using monoclonal antibody against the transferrin receptor to identify nucleated erythrocytes in the peripheral blood of pregnant women.
Female fetal cells in maternal blood: use of DNA polymorphisms to prove origin
TLDR
Genetic analysis can be performed on all fetal NRBCs, including female fetal cells that cannot be distinguished from maternal cells based on FISH analysis alone, and γ-positive female candidate fetal cells were determined to be fetal in origin.
Isolating fetal nucleated red blood cells from maternal blood: The baylor experience—1995
TLDR
Systematic evaluation of five glycophorin A (gly A) antibodies all produced agglutination, leading to the use of gly A antibodies for positive selection of fetal cells, and LDS‐751 to be useful for nuclear selection.
Diagnosing and preventing inherited disease: Nucleated erythrocytes in maternal blood: quantity and quality of fetal cells in enriched populations
TLDR
It was determined that less than one nucleated erythrocyte per ml of maternal blood was of fetal origin, suggesting that the fetal cells are less suitable for fluorescence in-situ hybridization (FISH) analysis than similar preparations from other sources.
PCR quantitation of fetal cells in maternal blood in normal and aneuploid pregnancies.
TLDR
The sixfold elevation of fetal cells observed in maternal blood when the fetus had trisomy 21 indicates that noninvasive cytogenetic diagnosis of trisomally normal fetuses should be feasible and feto-maternal transfusion of nucleated cells appears to be influenced by fetal karyotype.

TLDR
A concern about the use of identifying fetal cells in the maternal circulation of trophoblasts for noninvasive prenatal diagnosis is the making them available for a range of diagnostic fact that these cells are frequently multinucleate, which complicates interphase FISH.
Male fetal progenitor cells persist in maternal blood for as long as 27 years postpartum.
TLDR
The data demonstrate the continued maternal circulation of fetalCD34+ or CD34+CD38+ cells from a prior pregnancy, which may represent a human analogue of the microchimerism described in the mouse and may have significance in development of tolerance of the fetus.
Prenatal diagnosis of sickle cell anaemia and thalassaemia by analysis of fetal cells in maternal blood
TLDR
In two pregnancies at risk for sickle cell anaemia and β–thalassaemia, the fetal genotypes are successfully identified and prenatal diagnosis of single gene disorders by recovering fetal cells from maternal circulation appears to be a feasible approach.
