What kinds of tumor cells or biopsy specimens grow in vivo with Cultrex® BME?

Many cell lines and tumor biopsy specimens (usually cut into small fragments) have been found to grow in vivo when implanted with Cultrex® BME. These include melanoma, intestinal, prostate, breast, lung, renal, and liver cancers as well as the 3T3 mouse embryonic fibroblast cell line.

How does Cultrex® Basement Membrane Extract (BME) promote cell differentiation?

All epithelial and endothelial cells are in contact with a basement membrane matrix on at least one of their surfaces. By providing them with their natural matrix in vitro as a substrate for the cells that provides biological cues, the cells can assume a more physiological morphology (i.e. correct shape) and begin expression of cell-lineage specific proteins. Two-dimensional plastic surfaces, in combination with serum-containing media, cause cells to flatten, proliferate and de-differentiate.

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.
