Led by Dr. Sing Sing Way, the PRC is investigating the genetic and biological causes of preterm birth, having spearheaded a genome-wide study that identified six genes that may play a significant role in a woman's risk for preterm birth. The PRC’s other primary area of discovery is to examine the cross communication between the endocrine and maternal immune system, exploring how progesterone affects immune tolerance and serves as a unifying trigger of term and preterm birth.
Finally, the PRC is in the process of obtaining scientific, medical and societal insights from the co-creation of an African American birth cohort with Queens Village, a collective of more than 2,500 Black women committed to optimizing birth outcomes for Black women in Hamilton County, Ohio. The Queens Village cohort is conceived as a powerful tool for anticipated validation studies, mediation analyses and prospective testing of intervention strategies, all the while understanding the local context that shapes perspectives about research in the Black community.

We have genes for everything. Those genes, and their combinations and locations, determine everything that we are, from the color our eyes to perhaps even the emotions that color our thoughts. They’re the recipes our mothers used to build us. They tell us where—and who—we came from, along with all the potential traits and talents expressed by the people who will come from us. Is it possible then that there are genes that regulated the length of a pregnancy? This PRC theme explores the factors we may be born with that may lead to premature birth.
One of the most promising areas of inquiry in our search for the causes of and preventions for premature birth is the interaction between the mom and her microbiome, which is the community of microorganisms in her body. We know that inflammation as a result of infection is responsible for at least 50 percent of all cases of premature birth. And typically, that infection triggers a complex series of actions and reactions.
These include the activation of cells of the immune system, such as neutrophils, which can precipitate the physical transformations of collagen breakdown, cervical shortening, fetal membrane stretching, contractions and ultimately, premature labor and birth.
From the moment a woman gets pregnant, every system in a woman’s body begins undergoing profound changes, but perhaps none more so than her immune system. What’s fascinating is that the immune system, which is normally finely attuned to the presence of any foreign body however small, changes to achieve a delicate balance between tolerating the growing fetus—complete with its father’s antigens, which would normally be rejected—while still protecting the mother from infection.
During pregnancy, the immune system adapts right along with the growth of the fetus. The process is so precise that researchers believe that by tracking those changes and their interaction with the other systems (also being studied), we can gain an important new understanding not only of the gestational length of normal pregnancies, but also the potential signaling pathways that are triggered in the event of premature birth.
Identifying risk for preterm birth and getting the right care in the right place is key to saving lives. This PRC theme supports the development and exploration of biomarkers that indicate premature birth.
There are many components the blood of the mother and baby (for example, ribonucleic acid (RNA), deoxyribonucleic acid (DNA)). While DNA is like a blueprint of biological guidelines that a living organism must follow to exist and remain functional, RNA is what carry out this blueprint’s guidelines. It’s been known for decades that blood contains miniscule amounts of free-floating DNA and RNA released by dying or damaged cells throughout the body. Often this cell death represents natural cellular turnover; sometimes it’s the result of disease processes. But, until recently, analyzing this genetic material has been difficult due to its scarcity. Research in this area has led to promising diagnostics for early detection of preterm birth, preeclampsia, and other risks to the health of Moms and Babies.
The major success of the PRCs comes through the active collaboration and networking across centers. Sharing data & discoveries, while making connections across several themes requires integrating the work of researchers and clinicians from a broad range of disparate disciplines. More than 200 scientists, engineers, statisticians, sociologists and medical professionals work together to foster innovation that will accelerate discoveries of the unknown causes of preterm birth and new ways to prevent it. The March of Dimes Data Repository for Preterm Birth Research is truly the backbone of the research effort.
The Data Repository was designed to be both a catalog and catalyst. It provides the capability to ask new and important questions about preterm birth. Dedicated to enhancing research collaboration and coordination, the Data Repository currently contains information from 13 studies, with individual molecular profiles on 365 patients, aggregated genetic data from more than 30,000 patients, and molecular measurements on more than 8,000 samples. More data is being added every day, and the Data Repository’s contents were recently opened to all the other researchers studying preterm birth around the world, in an effort to encourage them to add their own findings to the Data Repository.
Making an Impact with Research
March of Dimes research is focused on making an impact NOW to end preventable preterm birth; we do this by approaching research in several key ways. At both the bench and bedside– through descriptive research that aims to characterize and understand the factors that lead to preterm birth and other adverse outcomes; and through work that leads to mitigation and prevention of preterm birth- through therapeutics, diagnostics, and/or policy changes.
We know that pregnancy is complex. March of Dimes research approach takes a whole-system view and brings the best talent and minds to bear, so we can make a difference in our lifetime.
- How are we making a difference: March of Dimes research programs have made discoveries that lead to direct impact on the health of moms, babies, and their families.
- PRC microbiome studies leading to bedside testing; rapid, low cost predictive testing.
- Early detection of preeclampsia and other adverse pregnancy outcomes through several approaches, including cell-free RNA, data analytics, and other diagnostic markers.
- Understanding maternal-infant nutrition, to wit, NEC and how breastfeeding can improve outcomes
