Summary for Cultrex Basement Membrane Extract, PathClear
Why Use Cultrex BME?
Cultrex Basement Membrane Extract (BME) is a soluble form of basement membrane purified from Engelbreth-Holm-Swarm (EHS) tumor. This extract provides a natural extracellular matrix hydrogel that polymerizes at 37°C to form a reconstituted basement membrane. Cultrex BME can be used in multiple applications, including maintaining growth or promoting differentiation of primary endothelial, epithelial, smooth muscle, stem cells, and organoid/3-D cell cultures. It can also be utilized in cell attachment, neurite outgrowth, angiogenesis, in vitro cell invasion, and in vivo tumorigenicity assays.
Basement membranes are continuous sheets of specialized extracellular matrix that form an interface between endothelial, epithelial, muscle, or neuronal cells and their adjacent stroma and that play an essential role in tissue organization by influencing cell adhesion, migration, proliferation, and differentiation. The major components of BME include laminin, collagen IV, entactin, and heparin sulfate proteoglycans.
