Fetal nucleic acids in maternal plasma: from biology to clinical translation

Area of Science:

• Environmental health
• Prenatal diagnostics
• Molecular biology

Background:

• Pregnancy exposure to environmental contaminants can disrupt fetal growth and programming.
• These disruptions can lead to immediate, lifelong, or transgenerational developmental disorders.
• Cell-free fetal nucleic acids in maternal plasma offer insights into fetal development.

Purpose of the Study:

• To review the utility of cell-free fetal nucleic acids as biomarkers for environmentally-associated fetal abnormalities.
• To discuss advancements in fetal nucleic acid analysis and quantification.
• To explore challenges and applications in fetomaternal medicine.

Main Methods:

• Literature review of studies on environmental contaminants and fetal development.
• Analysis of research on cell-free fetal nucleic acids in maternal plasma.
• Discussion of current and emerging methodologies for fetal nucleic acid detection.

Main Results:

• Cell-free fetal nucleic acids reflect in utero cellular changes, indicating normal or abnormal fetal development.
• These nucleic acids hold potential for developing biomarkers for screening environmental exposures.
• Recent advancements are improving analysis and quantification, though challenges remain.

Conclusions:

• Cell-free fetal nucleic acids are valuable tools for monitoring fetal health in the context of environmental exposures.
• Further research and technological development are needed to fully realize their potential in prenatal screening.
• These biomarkers could revolutionize fetomaternal medicine for early detection of environmental impacts.
