Thrombospondin modulates focal adhesions in endothelial cells
We examined the effects of thrombospondin (TSP) in the substrate adhesion of bovine aortic endothelial cells. The protein was tested both as a substrate for cell adhesion and as a modulator of the later stages of the cell adhesive process. TSP substrates supported the attachment of some BAE cells, but not cell spreading or the formation of focal adhesion plaques. In contrast, cells seeded on fi...
متن کاملFocal adhesions
What are they? Focal adhesions are the anchor points of the cell. These dynamic cytoskeletal structures are regions where the cell membrane firmly attaches to the extracellular matrix or the substratum. At the same time, focal adhesions provide scaffolding; they associate with an elaborate actin network inside the cell. Importantly, it’s now known that focal adhesions also act as communication ...
متن کاملMechanotransduction and focal adhesions.
Cellular FAs (focal adhesions) respond to internal and external mechanical stresses which make them prime candidates for mechanotransduction. Recent observations showed that the FA proteins including vinculin, FAK (FA kinase) and p130Cas are crucial for the ability of cells to transmit forces and to generate cytoskeletal tension. When mechanically stimulated, cells respond by modulating the spr...
متن کاملNitric oxide modulation of focal adhesions in endothelial cells.
A permissive role of nitric oxide (NO) in endothelial cell migration and angiogenesis promoted by vascular endothelial growth factor (VEGF), endothelin, and substance P has previously been established. The present studies were designed to examine the mechanism(s) involved in the NO effect on focal adhesions. Time-lapse videomicroscopy of human umbilical vein endothelial cells (HUVECs) plated on...
متن کاملAdrenomedullin and endothelial barrier function.
Although loss of endothelial barrier function is a hallmark of every acute inflammation and contributes to fatal loss of organ function during severe infections, there is no sufficient therapy for stabilization of endothelial barrier function. Endogenous peptide adrenomedullin (AM) serum levels were shown to be increased during severe infection including sepsis and septic shock. In different in...
