Placentation

Placental insufficiency during pregnancy is associated with memory alterations years after childbirth

A study by the Sant Pau Research Institute found that placental insufficiency during pregnancy is associated with higher risk of memory alterations years after childbirth. Women with angiogenic imbalance had a higher frequency of memory problems, even after accounting for other clinical factors.

New full-term placental stem cells could transform research on late-pregnancy complications

Researchers have successfully developed human placental stem cells from full-term pregnancies, sharing characteristics with early pregnancy cells. These Ch-TS cells can develop into key cell types essential for proper placental function, offering a more relevant model to study late-stage complications.

Human pregnancy dependent on cells evolved in platypus-like animal 300 million years ago

Research by UCL and Yale University reveals that platelet cells were crucial for the evolution of eutherian mammals, including humans. The discovery suggests that these cells enabled haemochorial placentation, allowing mothers to prevent haemorrhaging at birth.

Placental problems in early pregnancy associated with 5-fold increased risk of OB & fetal disorders

Researchers found that high uterine artery blood flow resistance in early pregnancy is associated with a 5-fold increased risk of preeclampsia, fetal growth restriction, and stillbirth. Increased cell death and reduced IGF2 expression may be causal factors of abnormal placental development.
