Summary
Preeclampsia may stem from excess anti-angiogenic factors like soluble fms-like tyrosine kinase 1 (sFlt1) and soluble endoglin (sEng). Measuring these angiogenic factors could aid in early preeclampsia diagnosis and risk identification.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Cardiovascular Biology
Background:
- Preeclampsia is a leading cause of maternal and neonatal complications globally.
- The exact causes of preeclampsia remain elusive, but placental dysfunction is implicated.
- Hypertension and proteinuria, key signs of preeclampsia, may result from an imbalance in angiogenic factors.
Purpose of the Study:
- To review the role of angiogenic factors in normal and abnormal placental development.
- To explore the potential of measuring circulating angiogenic factors for preeclampsia screening and diagnosis.
- To highlight how identifying women at risk of preeclampsia can improve obstetric care.
Main Methods:
- Review of recent scientific literature on preeclampsia and angiogenic factors.
- Analysis of the function of soluble fms-like tyrosine kinase 1 (sFlt1) and soluble endoglin (sEng).
- Discussion of the correlation between serum levels of sFlt1 and sEng and preeclampsia severity.
Main Results:
- Elevated levels of sFlt1 and sEng are observed in preeclamptic women.
- sFlt1 neutralizes key angiogenic growth factors, vascular endothelial growth factor and placental growth factor.
- sEng levels correlate strongly with the severity of preeclampsia.
Conclusions:
- Measurement of circulating sFlt1 and sEng may serve as a valuable diagnostic and screening tool for preeclampsia.
- Predictive tests for preeclampsia could significantly impact obstetric care and reduce mortality.
- Understanding angiogenic factor roles can help identify at-risk pregnancies early.

01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
01:10Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
01:33Hormonal Regulation
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.
01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:28Role of Hematopoietic Growth Factors
Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
