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

Why Use Cultrex Stem Cell Qualified RGF BME?

Cultrex Stem Cell Qualified RGF 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 Stem Cell Qualified RGF BME has been shown to provide an effective surface for feeder-free stem cell attachment and maintenance of undifferentiated human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs). It is useful for promoting the expansion of pluripotent stem cells or for the study of stem cell differentiation.

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.

Scientific Data Examples

	Cultrex BME Improves Hematopoietic Stem Cell Differentiation from Induced Pluripotent Stem Cells (iPSCs). Human iPSCs were grown for a minimum of 2 passages on either Cultrex Stem Cell Qualified RGF BME (Catalog # 3434-005-02) or a leading competitor's matrix, prior to creating embryoid bodies for hematopoietic stem cell differentiation. Cells pre-cultured on Cultrex Stem Cell Qualified RGF BME, showed a greater efficiency to develop into hematopoietic stem cells (CD34⁺, CD45⁺). Data courtesy of the Verneris Laboratory at the University of Colorado.
	Colonies of iPSCs Grown on Cultrex Stem Cell Qualified RGF BME. Human erythroblasts, reprogrammed into induced pluripotent stem cells (iPSCs), were cultured on plates coated with Cultrex Stem Cell Qualified RGF BME (Catalog # 3434-005-02). Example colonies are shown at 4X magnification. Data courtesy of the Harvard Stem Cell Core.
