Summary
This study maps the human maternal-fetal interface, revealing new cell types and molecular pathways. It identifies cells vulnerable to pregnancy complications, offering insights into placental development and disorders.
Area of Science:
- Reproductive Biology
- Genomics
- Developmental Biology
Background:
- The human maternal-fetal interface, crucial for pregnancy, involves complex interactions between maternal and fetal cells.
- Understanding the cellular, molecular, and spatial organization of this interface is essential but remains incomplete.
Purpose of the Study:
- To create a high-resolution, multiomic atlas of the human maternal-fetal interface across gestation.
- To define cell types, transcriptional programs, and spatial organization of the placenta and decidua.
- To identify cellular and molecular mechanisms underlying normal placental development and susceptibility to pregnancy complications.
Main Methods:
- Integrated large-scale single-nucleus transcriptomics, chromatin accessibility profiling, spatial transcriptomics, and multiplex protein imaging (CODEX).
- Generated a comprehensive, spatially resolved single-cell multiomic reference dataset.
- Utilized machine learning to predict cytotrophoblast invasiveness.
Main Results:
- Delineated common and transient cell types, states, and spatial niches within the maternal-fetal interface.
- Reconstructed transcriptional programs guiding cytotrophoblast and decidual stromal cell differentiation.
- Identified novel arterial endothelial cell transitions during spiral artery remodeling and a decidual stromal cell subtype suppressing cytotrophoblast invasion.
- Pinpointed maternal and fetal cells most vulnerable to pre-eclampsia, preterm birth, and miscarriage by integrating with GWAS data.
Conclusions:
- This atlas provides an unprecedented spatiotemporal, multiomic reference for the human placenta and decidua.
- The findings offer a framework for understanding normal placental development and decoding the origins of pregnancy disorders.
- Identified specific molecular pathways and cell subtypes involved in placental development and disease susceptibility.
