“…Although the overall VEGF signal was low in the placental beds of control women, the signal in decidual cells was much higher than the signal in villous trophoblasts and extravillous trophoblasts (EVTs; Figure 1, A and E). Furthermore, in preeclamptic women, there was a strong increase in VEGF expresproduction of VEGF in preeclampsia (12,(16)(17)(18)(19)(20). While there are reports of both increased and decreased levels of serum VEGF in preeclampsia, these differences may be explained by differences in methods used for measurement (6,18).…”

Figure 8. Effects of placental sFlt1 knockdown with or without endometrial VEGF overexpression. (A-L) Placental sFlt1 knockdown. Upon placentaspecific sFLT1 shRNA expression, widespread hemorrhaging in the fetus (B) and at the placental-decidual junction (D) was observed on GD18 compared with controls (A and C). Histological examination of sFLT1 shRNA-expressing placentas revealed extraordinary dilation of some maternal blood sinuses (arrowheads) in the labyrinth (E and F) and fibrin deposition (arrow) in these spaces (G and H). (I and J) MSB staining revealed extravasated fibrin (arrow) in adjacent areas. Placental sFlt1 knockdown did not affect implantation rate (K), whereas the fetal resorption rate significantly increased (L). (M-V) Placental sFlt1 knockdown enhanced the deleterious effects in Endo-VEGF animals. Pregnancies surviving to GD16 exhibited (M) excessive vaginal bleeding and (N-P) termination of pregnancy or resorption (arrows denote resorption sites) as well as (Q) widespread and extensive hemorrhaging in fetuses and placentas (arrowheads) and in deciduas at the maternal-fetal junction (asterisk). Histological examination (R-T) revealed widespread dilation and congestion of maternal blood sinuses (arrowheads) in the labyrinth, venous sinuses, and veins at maternal-fetal junctions, and MSB staining (U and V) demonstrated extensive fibrin extravasation (arrows) in the labyrinth and at the maternal-fetal junction. Results are mean ± SD. *P < 0.05 (n = 15). Scale bars: 2 mm (A-D); 500 μm (E, F, and R); 50 μm (G-J); 100 μm (S-V).

“…This state appears to result from an imbalance in the production and circulating concentrations of angiogenic factors such as placental growth factor (PlGF) and vascular endothelial growth factor (VEGF) and anti-angiogenic factors such as soluble VEGF receptor-1 (sVEGFR-1) and soluble endoglin (sEng). Elevated serum and plasma concentrations of sVEGFR-1 and s-Eng have been observed after the diagnosis of PE [1][2][3][7][8][9]11,12,15,18,19,[21][22][23] and before the recognition of clinical disease [4][5][6]10,13,14,16,17,20,30,32].…”

The change in concentrations of angiogenic and anti-angiogenic factors in maternal plasma between the first and second trimesters in risk assessment for the subsequent development of preeclampsia and small-for-gestational age, The Journal of Maternal-Fetal & Neonatal Medicine, 21:5, 279-287, DOI: 10.1080 AbstractIntroduction. An imbalance between angiogenic and anti-angiogenic factors has been proposed as central to the pathophysiology of preeclampsia (PE). Indeed, patients with PE and those delivering small-for-gestational age (SGA) neonates have higher plasma concentrations of soluble vascular endothelial growth factor receptor-1 (sVEGFR-1) and the soluble form of endoglin (s-Eng), as well as lower plasma concentrations of vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) than do patients with normal pregnancies. Of note, this imbalance has been observed before the clinical presentation of PE or the delivery of an SGA neonate. The objective of this study was to determine if changes in the profile of angiogenic and anti-angiogenic factors in maternal plasma between the first and second trimesters are associated with a high risk for the subsequent development of PE and/or delivery of an SGA neonate. Methods. This longitudinal case-control study included 402 singleton pregnancies in the following groups: (1) normal pregnancies with appropriate for gestational age (AGA) neonates (n ¼ 201); (2) patients who delivered an SGA neonate (n ¼ 145); and (3) patients who developed PE (n ¼ 56). Maternal plasma samples were obtained at the time of each prenatal visit, scheduled at 4-week intervals from the first or early second trimester until delivery. In this study, we included two samples per patient: (1) first sample obtained between 6 and 15 weeks of gestation ('first trimester' sample), and (2) second sample obtained between 20 and 25 weeks of gestation ('second trimester' sample). Plasma concentrations of s-Eng, sVEGFR-1, and PlGF were determined by specific and sensitive immunoassays. Changes in the maternal plasma concentrations of these angiogenesis-related factors were compared among normal patients and those destined to develop PE or deliver an SGA neonate while adjusting for maternal age, nulliparity, and body mass index. General linear models and polytomous logistic regression models were used to relate the analyte concentrations, ratios, and product to the subsequent development of PE and SGA. Results.(1) An increase in the maternal plasma concentration of s-Eng between the first and second trimesters conferred risk for the development of preterm PE and SGA (OR 14.9, 95% CI 4.9-45.0 and OR 2.9, 95% CI 1.5-5.6, respectively).(2) An increase in the maternal plasma concentration of sVEGFR-1 between the first and second trimester conferred risk for the development of preterm PE (OR 3.9, 95% CI 1.2-12.6). (3) A subnormal increase in maternal plasma PlGF concentration between the first and the second trimester was a risk factor for the subsequent development of preterm and term PE (OR 4....

“…A finding that was reported by a number of groups (Reuvekamp et al, 1999;Koga et al, 2003;Polliotti et al, 2003;Tsatsaris et al, 2003). In the contrast, also several studies exist, which described rising VEGF protein levels in the patients serum (Kupferminc et al, 1997;Shaarawy et al, 2005) or umbilical cord blood (Galazios et al, 2004).…”
