Flow cytometric methods for prenatal and neonatal diagnosis

Area of Science:

• Reproductive Biology
• Immunology
• Medical Diagnostics

Background:

• Current prenatal diagnostic methods like amniocentesis and chorionic villus sampling (CVS) have limitations.
• Flow cytometry offers a less invasive approach for fetal cell sorting from maternal circulation.
• Flow cytometry is the gold standard for diagnosing cellular immunodeficiencies.

Purpose of the Study:

• To review the advantages and disadvantages of MACS and FACS for fetal cell sorting.
• To provide an overview of flow cytometry assays and biomarkers for prenatal and neonatal diagnosis.
• To discuss the role of flow cytometry in monitoring post-transplant therapies.

Main Methods:

• Review of current literature on flow cytometry applications in prenatal and neonatal diagnostics.
• Comparison of magnetic-activated cell sorting (MACS) and fluorescence-activated cell sorting (FACS) for fetal cell isolation.
• Analysis of established flow cytometry assays and biomarkers for immunological and hematological abnormalities.

Main Results:

• Flow cytometry shows enhanced sensitivity in detecting fetal cells in maternal blood.
• Challenges remain for routine prenatal diagnostic application.
• Flow cytometry is crucial for diagnosing immunodeficiencies and monitoring transplant outcomes.

Conclusions:

• Flow cytometry is a versatile tool enhancing molecular and diagnostic testing in prenatal and neonatal care.
• It plays a key role in diagnosing immunological disorders and monitoring treatment efficacy.
• Further development is needed to fully integrate flow cytometry into routine prenatal diagnostics.
