  • vascular permeability was present at all measurements for both vessels and its magnitude directly proportional to the intravascular pressure. (bvsalud.org)
  • Changes in vascular permeability are lial cells tethered together by junctional proteins commonly present in certain clinical diseases such as tight and adherens junctions. (bvsalud.org)
  • The vascular endothelium produces a number of important substances including endothelial-derived relaxing factor or nitric oxide, endothelin-1, prostacyclin, and tissue plasminogen activator. (health.am)

  • Thus, it has been shown that early EPCs release cytokines that promote tissue regeneration and neovasculogenesis, whereas late EPC and endothelial colony forming cells (ECFCs) contribute to the formation of blood vessels and stimulate tube formation. (intechopen.com)
  • It was identified as a gene that was up-regulated four-to-six fold during early blood vessel formation and found to promote the growth of new blood cells from the existing vessels. (fazendomedia.com)
