basal expression of tissue plasminogen activator is not affected by any of the proinflammatory cytokines TNF-alpha, IL-1beta and IFN-gamma individually or in combination, no increase in tissue plasminogen activator synthesis is observed by ELISA when cells are stimulated with viral polyriboinosinic:polyribocytidylic acid RNA for 3 and 6 h, both with and without cytokine pretreatment |

for hemostatic function of endothelial cells, tissue plasminogen activator secretion by Puro-selected endothelial cells are measured with or without shear stress exposure. Tissue plasminogen activator, which has fibrinolytic function, is known to increase with exposure to shear stress. Free tissue plasminogen activator level is increased in Tie1- and platelet endothelial cell adhesion molecule promoter-driven Puro-selected cells, but Flk1 and vascular endothelial-cadherin promoter-driven cells show the opposite trend. The levels of free tissue plasminogen activator in embryonic stem cell-derived cells are much higher than that of EOMA cells in general. plasminogen activator inhibitor-1 secretion by these cells can be estimated by comparing the ratio between free and total tissue plasminogen activator because total tissue plasminogen activator reflects plasminogen activator inhibitor-1 bound as well as free tissue plasminogen activator. Abnormally high plasminogen activator inhibitor-1 secretion indicates by high bound tissue plasminogen activator in EOMA cells can result from in vitro culture conditions of EOMA in its proliferative state, because quiescent endothelial cells have very low plasminogen activator inhibitor-1. Higher free/total tissue plasminogen activator ratio in embryonic stem cell-derived endothelial cells indicates lower plasminogen activator inhibitor-1 level in these cells, and thus these cells may be closer to quiescence |

influence of endothelial cells on astrocytic gene expression of t-PA using an in vitro model of the blood-brain barrier, primary rat astrocyte-enriched cultures are cocultured with primary adult rat brain microvascular endothelial cells on opposite sides of a transwell membrane, after co-culturing for 9-11 days, the cultures are treated with lipopolysaccharide for 8 h or 24 h, t-PA mRNA expression in astrocytes are unaffected by co-cultivation and/or lipopolysaccharide treatment, analysis of endothelial t-PA gene expression reveals increased unaltered t-PA mRNA levels |
