The vascular barrier is essential to maintain the selective permeability, which is important for proper organ development and performance and its dysfunction is involved in several diseases. Endothelial cell lining of the internal vasculature forms a semi-permeable barrier that is essential in selective transport between the blood and the interstitial spaces of the body. An adequate permeability barrier function is governed by cell-cell, cell-extracellular matrix contacts and inflammatory factors. Disruption of the endothelial cell barrier can result in increased permeability and vascular leakage, which is associated with many systemic diseases and pathological angiogenic diseases. The studies of the underlying molecular mechanisms require multidisciplinary method. Here, Creative Proteomics establish a method to measure vessel permeability in vitro.
Figure 1. The process of Vascular Permeability Assay
The vascular permeability assay provides an efficient and convenient system to evaluate the effects of chemicals and drugs on endothelial cell adsorption, transport and permeability. This assay is also effective and versatile to study various compounds that influence the permeability of endothelial cells. Thus, with the help of vascular permeability assay, it is more easily and possible to obtain a further understanding of the mechanisms of vascular permeability.
