Maps cell interactions and identifies vulnerable cells in the placenta during pregnancy, highlighting implications for complications.
The placenta — a temporary organ of the offspring — attaches to the mother’s uterus, from which it taps a blood supply. A high-resolution map of individual cells at this junction now reveals some of the specific cell–cell interactions involved and pinpoints cell types that are vulnerable in common pregnancy complications. A study of the placental–uterine connection has characterized known and previously unknown cell types and states.
