To investigate the cellular, molecular, and transcriptomic changes occurring in the smooth chorion cytotrophoblasts of fetal membranes in pregnancies affected by severe preeclampsia.
Examined smooth chorion tissue from the fetal membranes of severe preeclampsia pregnancies.
Conducted transcriptomic profiling and cellular assays to evaluate stage-specific antigen expression, oxidative stress markers, and regulatory pathways involving PAPPA1 and IGF1.
Severe preeclampsia induced significant expansion of the smooth chorion cytotrophoblast layer and enhanced expression of stage-specific extravillous differentiation antigens.
Transcriptomics showed dysregulation of placental proteins and oxidative stress markers, alongside elevated PAPPA1 expression that released IGF1 to drive cytotrophoblast proliferation.

Implication

Molecular analysis demonstrates smooth chorion cytotrophoblast expansion in severe preeclampsia, suggesting a compensatory response to defective placentation.
