Thrombin stimulation of prostacyclin (PGI,) synthesis by cultured human umbilical vein endothelial cells (HUVEC) requires the active site of thrombin and involves rapid and transient rises in cytoplasmic free calcium [CaL+],. In this study, we investigated whether or not the anion-binding exosite fo

Abstract
Endothelial cell layer regulates several crucial physiological processes of the vascular system. The mechanism of the response of this cell layer to the flow of surrounding fluid is still largely unclear. In the present article, a comparison of the available experimental results for the intracellular calcium ion concentration and theoretical results for the extraβcellular ATP concentration obtained using a convectiveβdiffusive mass transfer model, has been made which supports the mass transfer model for the endothelial cell response to the fluid flow. The experimental results are in excellent agreement with the calculated values assuming the effect of ATP concentration alone. Biotechnol. Bioeng. 2008;101: 843β849. Β© 2008 Wiley Periodicals, Inc.

Vascular endothelial cells respond to a variety of physiological and pharrnacological stimuli by releasing free arachidonic acid from membrane phospholipids, thus initiating synthesis of prostacyclin. Previous work in our laboratory has demonstrated that the thrombin-stimulated deacylation is specif
