Epithelial-mesenchymal transition during extravillous trophoblast differentiation

Area of Science:

• Reproductive Biology
• Developmental Biology
• Cellular Biology

Background:

• Successful pregnancy relies on complex maternal-fetal cell interactions.
• Placental extravillous cytotrophoblast invasion requires a shift from epithelial to mesenchymal phenotype.
• Villous cytotrophoblasts partially undergo epithelial to mesenchymal transition (EMT) for migration and invasion.

Purpose of the Study:

• To review known regulators of EMT in the human placenta.
• To examine EMT's role in pregnancy pathologies like preeclampsia (PE) and fetal growth restriction (FGR).
• To explore potential therapeutic strategies targeting placental EMT.

Main Methods:

• Literature review of EMT inducers, transcription factors, and downstream effectors.
• Analysis of cell adhesion molecules' differential expression in PE and FGR.
• Description of in vitro research strategies for identifying EMT target functions.

Main Results:

• EMT regulators, transcription factors, and cell adhesion molecules are key to placental development.
• Differential expression of these factors is implicated in PE and FGR.
• In vitro studies aid in understanding EMT target functions.

Conclusions:

• Understanding placental EMT pathways is vital for fetal development.
• Elucidating EMT signaling may offer novel therapeutic targets for placental pathologies.
• Targeted therapies could improve feto-placental growth in conditions like PE and FGR.
