In human blastocyst-derived placental stem cell–derived syncytiotrophoblasts, 24 h at 1% O2 most consistently reproduces PE-like dysfunction, including sFlt-1/sEng induction and increased cell death.
- Why it matters: Hypoxia models of preeclampsia-associated syncytiotrophoblast dysfunction vary widely in oxygen control and exposure timing, limiting standardization and comparability across in vitro studies.
- What they did: The authors differentiated human blastocyst-derived trophoblast stem cells into STs and exposed them to 8% O2, 21% O2, or 1% O2 for 24 or 48 h, then measured angiogenic/apoptotic markers, cell death, and mitochondrial stress.
- The result: Relative to 21% O2, 8% O2 reduced cell death and better matched physiological ST conditions, while several PE-like marker changes after 1% O2 were attenuated or reversed after prolonged exposure.
