This study deciphers maternal-fetal communication during labor using single-cell RNA sequencing. Placenta-derived signatures in maternal circulation may predict spontaneous preterm birth, offering potential for noninvasive biomarkers.
Area of Science:
- Reproductive biology
- Genomics
- Obstetrics
Background:
- Maternal-fetal cross-talk is crucial for labor but poorly understood at the cellular level.
- Previous studies lacked detailed cellular insights into placental communication during parturition.
Purpose of the Study:
- To elucidate maternal-fetal signaling in the human placenta during term labor using single-cell RNA sequencing.
- To identify placenta-derived signatures in maternal circulation for potential preterm birth prediction.
Main Methods:
- Single-cell RNA sequencing (scRNA-seq) of human placenta during term labor.
- Cell-cell interaction analysis to identify signaling pathways.
- Integration with bulk transcriptomic data and analysis of maternal circulation.
Main Results:
- Single-cell atlas revealed labor-induced transcriptomic changes in maternal decidual, fetal stromal, and myeloid cells.
- Identified key signaling pathways (collagen, CXCL, TNF, galectin, IL-6) involved in labor.
- Placenta-derived signatures detected in maternal circulation, mirroring term and preterm labor.
Conclusions:
- Single-cell signatures provide insights into maternal-fetal cross-talk during human parturition.
- Placenta-derived signatures in maternal circulation show promise for noninvasive prediction of spontaneous preterm birth.
