“…In the samples from the pregnant women, FISH with GMGY1O and DXZ1 showed four male pregnancies and one female pregnancy (figure D,F). Fetal sex determined in this way was in exact agreement with the cytogenetic analysis of amniotic fluid samples (table 3). …”

Fetal nucleated cells in the maternal circulation constitute a potential source of cells for the non-invasive prenatal diagnosis of fetal genetic abnormalities. We have investigated the use of the Magnetic Activated Cell Sorter (MACS) for enriching fetal nucleated erythrocytes. Mouse monoclonal antibodies specific for CD45 and CD32 were used to deplete leucocytes from maternal blood using MACS sorting, thus enriching for fetal nucleated erythrocytes which do not express either of these antigens. However, significant maternal contamination was present even after MACS enrichment preventing the accurate analysis of fetal cells by interphase fluorescence in situ hybridisation (FISH). To overcome this problem, we used simultaneous immunophenotyping of cells with the mouse antifetal haemoglobin antibody, UCHy, combined with FISH analysis using chromosome X and Y specific DNA probes. This approach enables selective FISH analysis of fetal cells within an excess of maternal cells. Furthermore, we have confirmed the potential of the method for clinical practice by a pilot prospective study of fetal sex in women referred for amniocentesis between 13 and 17 weeks of gestation.

“…Normal human whole blood consists of red blood cells (RBCs) (5-9 × 10 9 ml −1 ), white blood cells (WBCs) (5-10 × 10 6 ml −1 ) and platelets (2.5-4 × 10 8 ml −1 ). The absolute number of fetal cells has yet to be established but their frequency has been estimated to be between one to two fetal cells per ml of maternal blood [26,27], or 1 in 10 5 -10 7 maternal cells [28]. The number of fetal cells has also been shown to increase in abnormal pregnancies which is believed to be due to an impaired placenta, leading to an increase in maternal-fetal transfusion [29,30].…”

“…The most commonly used antigens are Cluster of Differentiation, CD71 (transferrin receptor) [45], CD36 (thrombospondin receptor), glycophorin A (GPA) [46,28]. Fetal leukocytes were the first fetal cells to be separated by FACS in 1979 by Herzenberg et al [47], based on differences in human leukocyte antigen (HLA) expression.…”

A modern flow cytometer can analyze and sort particles on a one by one basis at rates of 50,000 particles per second. Flow cytometers can also measure as many as 17 channels of fluorescence, several angles of scattered light, and other non-optical parameters such as particle impedance. More specialized flow cytometers can provide even greater analysis power, such as single molecule detection, imaging, and full spectral collection, at reduced rates. These capabilities have made flow cytometers an invaluable tool for numerous applications including cellular immunophenotyping, CD4+ T-cell counting, multiplex microsphere analysis, high-throughput screening, and rare cell analysis and sorting. Many bio-analytical techniques have been influenced by the advent of microfluidics as a component in analytical tools and flow cytometry is no exception. Here we detail the functions and uses of a modern flow cytometer, review the recent and historical contributions of microfluidics and microfabricated devices to field of flow cytometry, examine current application areas, and suggest opportunities for the synergistic application of microfabrication approaches to modern flow cytometry.
