Vascular endothelial cells contribute to the maintenance of vascular homeostasis. Vascular endothelial cells produce and secrete activators and inhibitors of the coagulation and fibrinolysis system. In addition, they mediate the adhesion and aggregation of blood platelets. Endothelial cells also release molecules that regulate cell proliferation and control vessel wall tone. Human umbilical vein endothelial cells (HUVEC) are the type of cells most used in the study of endothelial cell processes. HUVEC have a “cobblestone” morphology, show positive staining for vWF/Factor VIII and CD-31, and the ability to take up acetylated low-density lipoprotein. Cells pretreated with IL-1 or TNF-alpha also selectively express E-selectin and VCAM.
About turboGFP protein:
tGFP is an improved variant of the green fluorescent protein CopGFP from copepoda Pontellina plumata (Arthropoda; Crustacea; Maxillopoda; Copepoda). It possesses bright green fluorescence (excitation/ emission max = 482/ 502 nm) that is visible earlier than fluorescence of other green fluorescent proteins. TurboGFP is useful for applications where fast appearance of bright fluorescence is crucial. It is also useful for cell and organelle labeling and tracking the promoter activity.
