General description
Introduction
Angiogenesis is the process of generating new capillary blood vessels. It is a fundamental component of a number of normal (reproduction and wound healing) and pathological processes (diabetic retinopathy, rheumatoid arthritis, tumor growth and metastasis)1.
The CHEMICON Fibrin Gel In Vitro Angiogenesis Assay Kit provides a convenient system for evaluation of tube formation by endothelial cells in 96-well or other formats. When cultured on top or within a fibrin gel, endothelial cells rapidly align and form interconnecting networks that can display patent lumina2,3. Tube formation is a multi-step process involving cell adhesion, migration, differentiation and growth4. The formation of intercellular connections and lumina within endothelial cell networks in fibrin gels is dependent upon the actions of VE-cadherin, avb3 and a5b1 integrins, the cdc42 and Rac1 GTPases, and membrane-type matrix metalloproteinases (MT-MMPs)2,3,5,6. Angiogenesis within fibrin gels in vitro is regarded as an accurate model for wound healing and tumor angiogenesis, as tumor cell-derived vascular endothelial growth factor/vascular permeability factor promotes leakage of fibrinogen from the tumor vasculature and formation of a fibrin-rich proangiogenic provisional matrix7.
Fibrin gel formation is initiated by enzymatic cleavage of fibrinogen, a heterotrimer, by thrombin8. The resulting cleaved fibrin molecules form regular, multimolecular arrays that are highly translucent. The concentrations and formulations of the fibrinogen and thrombin in this kit are optimized for maximal tube-formation by HUVEC and easy visualization of these tubes.

Application
Application
The CHEMICON Fibrin Gel In Vitro Angiogenesis Assay Kit represents a simple model of angiogenesis in which the induction or inhibition of tube formation by exogenous signals can be easily monitored. Fibrin gels are easily and quickly formed in culture dishes by mixing Fibrinogen and Thrombin Solutions. For assaying inhibitors or stimulators of tube formation, simply premix the endothelial cell suspension with different concentrations of the inhibitor or stimulator to be tested, before adding the cells to the top of the fibrin gel. Addition of a second layer of fibrin gel on the day after plating the cells is optional, but will promote optimal survival and a higher degree of network and lumen formation. The assay can be used to monitor the extent of tube assembly in various endothelial cells, e.g. human umbilical vein cells (HUVEC) or bovine capillary endothelial (BCE) cells.
