- Primary Outcome Measures
Name Time Method <p>The vascular reactivity of arteries from omental tissue, subcutaneous fat and<br /><br>placental tissue will be studied using 1) wire myography to assess vascular<br /><br>contractions and relaxations to agonists, as well as the effects of antagonists<br /><br>on these contractions and relaxations, 2) pressure myography to assess vascular<br /><br>distensibility and flow-mediated vasodilation, 3) biomarker concentrations in<br /><br>maternal and umbilical cord blood, 4) molecular response of placental and<br /><br>vascular cell types.</p><br>
- Secondary Outcome Measures
Name Time Method <p>- To determine if and how alterations in maternal vascular reactivity correlate<br /><br>with alterations in foetoplacental vascular reactivity.<br /><br>- To examine whether (novel) therapeutics can restore this altered response.<br /><br>- To determine if and how alterations in maternal and placental vascular<br /><br>reactivity correlate with biomarker concentrations in maternal blood an<br /><br>umbilical cord blood.<br /><br>- To detect placental alterations at the tissue level and at the molecular<br /><br>level for different cell types contributing to the maternal-placental<br /><br>interface. </p><br>
