New Atlas Unveils Hidden Cells in Pregnancy
10 Apr
Summary
- Scientists mapped placenta and uterus tissues throughout pregnancy.
- A new cell subtype unique to pregnancy was discovered.
- These cells may link placenta to maternal blood supply.
A groundbreaking atlas detailing the placenta and uterus throughout pregnancy has been unveiled by scientists. This comprehensive map offers a unique cellular and molecular perspective on how these vital tissues develop to support fetal growth.
The research identified a novel cell subtype exclusively present during pregnancy. These cells emerge as the uterine lining transforms to cradle the embryo and are suspected to be involved in linking the placenta to the maternal blood supply. Researchers are investigating their connection to cannabinoids and potential links to cannabis use during pregnancy.
This extensive atlas, compiled from millions of placental and uterine cells collected between weeks 5 and 39 of gestation, provides a detailed timeline. By integrating gene activity and protein presence data with cellular location, the study illuminates the precise regulation of crucial processes, such as fetal cell invasion into the uterine arteries, which is vital for healthy pregnancy outcomes.
