How mucus-producing cervical cells protect against infection in pregnancy
Functional and Molecular Characterization of Epithelial Subtypes in Cervical Remodeling and Preterm Birth
This project looks at mucus-producing cervical cells in pregnancy to find markers that could signal which pregnant women are at higher risk for infection-related preterm birth.

What this research studies
Researchers use mouse models and advanced single-cell and spatial gene-expression techniques to map distinct cervical epithelial cell types that appear during pregnancy. They will trace the origin of two mucus-secreting goblet cell populations and define how progesterone and estrogen control their growth and differentiation. The team will model barrier defects and inflammation in mice to see which epithelial changes allow bacteria to ascend and trigger preterm birth. Finally, they will measure an immune protein called olfactomedin 4 in cervicovaginal fluid from pregnant women across trimesters to see if it reflects cervical epithelial health and links to preterm birth risk.
Who could benefit from this research
Good fit: Pregnant women willing to provide cervicovaginal fluid samples across trimesters, especially those concerned about or at risk for preterm birth, would be ideal candidates.
Not a fit: People who are not pregnant or whose preterm birth risk is unrelated to ascending infection or cervical epithelial health are unlikely to directly benefit from this work.
Why it matters
Potential benefit: If successful, this work could lead to a vaginal-fluid biomarker or new targets to prevent infection-driven preterm birth.
How similar studies have performed: Single-cell mapping of reproductive tissues has produced promising insights, but using goblet-cell markers and olfactomedin 4 in vaginal fluid as a clinical predictor of infection-related preterm birth is relatively novel.
