The contractile responses of cultured rat and calf endothelial cells (EC), vascular smooth muscle cells (VSMC), and fibroblasts (FB) to vasoactive mediators (thrombin, serotonin, bradykinin, and histamine), forskolin, and cytochalasin B were compared. Cells were grown on a pliable silicone membrane, and contraction was assessed, using time-lapse video(More)
In this study, we demonstrate that vaccination of rabbits with murine endothelial cells yields polyclonal immunoglobulin (IgG) with potent antiangiogenic activity. The mechanism of this response appears to be through apoptosis of endothelial cells in vitro. Induction of polyclonal IgG in a xenogeneic host may be useful in passive immunotherapy of a variety(More)
Endothelial cells (EC) cultured on polymerized silicone deform the underlying substrate, producing microscopically visible wrinkles. This has been interpreted as cellular contraction, and we have previously concluded that EC normally maintain an active contractile tone. Since in ischemic tissues capillaries become "paralyzed" and lose their tone, we decided(More)
During angiogenesis, the microvasculature displays both vessel remodeling and expansion under the control of both cellular and extracellular influences. We have evaluated the role of angiogenic and angiostatic molecules on angiogenesis in anin vitro model that more appropriately duplicates the cellular and extracellular components of this process.
