Electron micrographs of human
umbilical vein endothelial cells (HUVECs) in each group.
Endothelial microparticlehypoxia-inhibited migration and angiogenesis of human
umbilical vein endothelial cells
Computerized Tomography (CT) scan of her abdomen and pelvis with contrast (Figure 1) was performed to confirm our diagnosis but instead it revealed a thin-walled gall bladder, stranding adjacent to the pancreatic tail and a 3 cm reduced attenuation structure, which was thought to represent an acute thrombosis of the
umbilical vein. There was no evidence of collection.

Intriguingly, eNOS protein abundance and activator phosphorylation ([Ser.sup.1177]) are higher in HUVECs from LOPE pregnancies [20], findings complemented by elevated nitrate/nitrite ratio in human
umbilical vein serum [62, 63], but contrary to the reported lower nitrate/nitrite ratio [64] and NOS-generation of L-citrulline from L-arginine (index of NOS activity) [20] in this cell type.
miR-222, firstly discovered in human
umbilical vein endothelial cells (HUVECs), has been reported to play important roles in epithelial tumors evidenced by its frequently increased expressions in epithelial tumors [9].
Therefore, it has no clinical values.2,3 Velamentous umbilical cord entry locates at free embryonic membrane outside the placental edge, and
umbilical vein twists through amnion and chorion and then goes deep in the placenta.4 Without the protection of wharton jelly, the rupture and embolization of umbilical vessels are more likely to happen.
Colour Doppler sonography revealed the
umbilical vein draining into the portal sinus with non-visualisation of the DV, which would connect the portal sinus with the inferior vena cava (IVC) (Figs 1C and 1D).
