Background: Basement Membrane Extracts
3-D Culture is a cell culture method that provides cells with the
necessary structure and signaling cues to direct reconstruction of the
tissue architecture, and these methods provide physiologically
predictive in vitro models for evaluating development and disease.
Normal cells assemble into organiods that structurally resemble their
emanating tissues, exhibit a polarized morphology, undergo cell cycle
regulation, and produce tissuespecific proteins. While cancer cells
assemble into tumor-like structures, lacking an organized architecture
or cell cycle regulation and exhibiting tumor-specific markers depending
on the extend of malignancy.
To aid in the advancement of this technology, Trevigen has developed Cultrex®
3-D Culture Matrix™ RGF BME which is the first Basement Membrane
Extract produced and qualified specifically for use in 3-D culture
studies. The 3-D Culture Matrix™ RGF BME provides the foundation for
cells to grow in three dimensions allowing for the formation of
structures in vitro. To provide the most standardized basement
membrane extract for use in 3-D cultures, a special process is employed
to reduce growth factors and manufacture matrix at a standard
concentration of approximately 15 mg/ml. This product is then evaluated
in a 3D culture to validate efficacy.

How does Cultrex® 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 substrates, in combination with serum-containing media, cause cells to flatten, proliferate and de-differentiate.
