P2X4 and P2X6 receptors associate with VE-cadherin in human endothelial cells
We investigated the expression of P2X4 and P2X6 receptors on human umbilical vein endothelial cells (HUVECs) and found that both P2X receptor subtypes on plasma membranes are largely restricted to areas of cell-...

Electron-microscopic immunolabelling of vasoactive substances in human umbilical endothelial cells and their actions in early and late pregnancy
Human umbilical vessels are devoid of nerves and therefore endothelial cells may play an important role in the control of feto-placental blood flow. The pharmacological effects of 5-hydroxytryptamine, histamin...
