Basement membrane extract (BME) is a type of extracellular matrix (ECM) derived from Engelbreth-Holm-Swarm mouse sarcomas. BME is commonly used in cell culture and tissue engineering to provide a 2-D or 3-D scaffold for cells, allowing them to grow, differentiate, and interact in an environment that closely mimics the native ECM. This makes BME invaluable for modeling the behavior of cells in vivo. All Cultrex BME formulations are rigorously tested to ensure performance, quality, and lot-to-lot consistency.

Product Summary for Cultrex Basement Membrane Extract, Type 3, Pathclear
Why Use Cultrex BME, Type 3?
Cultrex Basement Membrane Extract (BME), Type 3 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, Type 3 provides a proprietary formulation that is physiologically aligned with the in vivo solid tumor environment and is recommended for xenografts and other in vivo applications. This extracellular matrix hydrogel is designed to help cells to adapt to in vivo transplantation. It mimics the in vivo microenvironment, including low glucose and low pH, to improve take rate and growth of implanted cells for xenograft and tumorgraft models.
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.
