DDAVP and epinephrine-induced changes in the localization of von Willebrand factor antigen in endothelial cells of human oral mucosa.

چکیده
A peroxidase-labeled antibody technique revealed von Willebrand factor antigen (vWF:Ag) in rough endoplasmic reticulum (rER), the perinuclear region, and the cytoplasmic vesicles of capillary endothelial cells in oral mucosa. After administration of epinephrine or 1-deamino-8-D-arginine vasopressin (DDAVP), the localization of vWF:Ag was shown to have changed to the basement membrane and the surrounding interstitium. This change of vWF:Ag localization induced by epinephrine and DDAVP may play a role in the adhesion of platelets to subendothelium following endothelial injury during surgery and may be an unknown hemostatic effect of these drugs.

3D study of capillary network derived from human cord blood mesenchymal stem cells and differentiated into endothelial cell with VEGFR2 protein expression
New blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ECs) which in turn give rise to primitive capillary network. Human cord blood (HCB) contains large subsets of mononuclear cells (MNCs) that can be differentiated into endothelial-like cells in vitro. Human mononuclear progenitor cells were purified from fresh umb...
متن کاملCapillary Network Formation by Endothelial Cells Differentiated from Human Bone Marrow Mesenchymal Stem Cells
Human bone marrow derived mesenchymal stem cells (HBMSCs) have the potential to differentiate into cells such as adipocyte, osteocyte, hepatocyte and endothelial cells. In this study, the differentiation of hBMSCs into endothelial like-cells was induced in presence of vascular endothelial growth factor (VEGF) and insulin-like growth factor (IGF-1). The differentiated endothelial cells were exam...
متن کاملVasopressin-induced von Willebrand factor secretion from endothelial cells involves V2 receptors and cAMP.
Vasopressin and its analogue 1-deamino-8-D-arginine vasopressin (DDAVP) are known to raise plasma von Willebrand factor (vWF) levels. DDAVP is used as a hemostatic agent for the treatment of von Willebrand's disease. However, its cellular mechanisms of action have not been elucidated. DDAVP, a specific agonist for the vasopressin V2 receptor (V2R), exerts its antidiuretic effect via a rise in c...
متن کاملVascular Endothelial Growth Factor Expression in Oral Lichen Planus: A Comparative Study
Background and aim: Lichen planus (LP) is a chronic inflammatory disease with an uncertain pathogenicity. Recent reports have revealed that angiogenesis is effective in the pathogenesis and biologic behavior of lesions. Considering the limitations of the studies related to angiogenesis in oral LP (OLP) and the controversial results, the present study aimed to compare the expression of vascular ...
متن کاملThe effect of DDAVP on plasma levels of von Willebrand antigen II in normal individuals and patients with von Willebrand's disease.
The infusion of 1-deamino-(8-D-arginine)-vasopressin (DDAVP) causes not only an elevation in factor VIII-related antigen (FVIIIR:Ag), but also a marked elevation of plasma von Willebrand antigen II (vWAgII). vWAgII reaches a peak concentration at 60 min and is elevated 3-8-fold over basal levels in normal individuals and individuals with type I, IIA, and IIB von Willebrand's disease. As the mec...
