New Insights into Amniotic Fluid: Critical for Fetal Development and Maternal Health

Recent research from Oregon Health & Science University (OHSU) has shed new light on the role of amniotic fluid, a substance that has long posed challenges for medical study due to its inaccessibility during various stages of pregnancy. This new study aims to enhance understanding of amniotic fluid’s functions and properties, particularly in relation to blood coagulation.

Amniotic fluid is essential for the protection and development of a fetus in utero. It cushions the fetus, facilitates organ development—especially the lungs, digestive system, and skin—and helps maintain a stable temperature within the womb.

Published in the journal Research and Practice in Thrombosis and Haemostasis, the recent findings suggest that amniotic fluid enhances the clotting capabilities of plasma, the liquid component of blood. This function is vital for the health of both the birthing individual and the fetus throughout pregnancy and during delivery, highlighting the fluid’s potential to serve as a protective agent in critical situations.

While previous knowledge has established the importance of amniotic fluid in fetal development, little was known about its properties over the course of pregnancy. The OHSU study represents a significant step in investigating how these properties evolve and how they influence maternal blood coagulation. Inadequate blood clotting during pregnancy can lead to serious complications, including excessive bleeding, which poses risks to both mother and child.

According to Dr. Jamie Lo, the study’s lead author and an associate professor of obstetrics and gynecology at OHSU, “Our research indicates that while we have recognized the significance of amniotic fluid, there is much more to uncover. We found that its composition, particularly the proteins it contains, shifts to meet the developing fetus’s needs.” This prompted further investigation into the protective properties of amniotic fluid and its potential future therapeutic applications.

This interdisciplinary study involved collaboration among experts from various fields, including Dr. Chih Jen Yang, Dr. Lyndsey Shorey-Kendrick, Dr. Joseph Shatzel, Dr. Brian Scottoline, and Dr. Owen McCarty.

The research team analyzed amniotic fluid obtained through amniocentesis—a prenatal diagnostic procedure that samples amniotic fluid to assess pregnancy health—comparing samples from both human and non-human primates at similar gestational stages. The analysis revealed that amniotic fluid promotes blood clotting through key fatty acids and proteins, which vary across the trimesters and play an integral role in coagulation regulation.

With evidence suggesting that amniotic fluid may hold untapped potential for diagnosing and managing various prenatal conditions, the research team is now working alongside Dr. Sanjay Malhotra to investigate pregnancy disorders, particularly those affecting blood and blood-producing organs, that might benefit from the therapeutic properties of amniotic fluid constituents.

The researchers are also collaborating with OHSU’s Fetal Care Program to collect distinctive amniotic fluid samples, particularly from pregnancies undergoing in-utero repairs for neural tube defects, such as spina bifida. Their aim is to determine if these unique samples contain developmental factors that could be targeted for future medical interventions to improve health outcomes.

As interest in the study of amniotic fluid grows, the researchers express enthusiasm about the potential health benefits it could provide for mothers and babies alike. Dr. Brian Scottoline, co-senior author of the study, emphasizes the importance of understanding how amniotic fluid functions: “Babies born prematurely miss out on vital developmental time in amniotic fluid. A deeper understanding of its composition and roles could pave the way for innovative therapies.”

Dr. Lo also highlighted a fascinating possibility: “Through our research, we’re beginning to view amniotic fluid as a precursor to breast milk, akin to ‘pre-term’ milk for a fetus. If we can harness the properties of amniotic fluid, there may be potential to develop formulas for preterm infants that could facilitate growth and mitigate complications associated with premature birth. This research is just the beginning of what may be possible.”
