• Commonly used robust and established organoid systems
• Reduced growth factor formulation provides a more defined culture system
• Quality controlled for performance consistency

Why Use Cultrex RGF BME, Type 2 Select?

Cultrex Reduced Growth Factor Basement Membrane Extract (RGF BME), Type 2 Select 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. 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 heparan sulfate proteoglycans. Negative for the presence of bacteria and fungi.

Cultrex RGF BME, Type 2 provides a proprietary formulation that has a high storage modulus and is designed for use in robust tissue organoid culture as well as other applications requiring an extracellular matrix scaffold.

Protocols Utilizing Cultrex RGF BME, Type 2 Select for Organoid Cell Culture.

Cultrex RGF BME, Type 2 Select is ideal for use as a scaffold for organoid and 3D cell culture. Listed below are protocols designed by our research and development groups for organoid culture featuring Cultrex RGF BME, Type 2 as well as growth factors, media supplements, and small molecules from Bio-Techne.

Mouse Intestinal Organoids Cultured in Cultrex RGF BME, Type 2. Mouse intestinal organoids cultured in Cultrex RGF BME, Type 2 were immersion fixed and processed for whole mount staining or paraffin embedding and sectioning for immunocytochemistry. A) Whole mount mouse intestinal organoids were stained using Goat Anti-Human/Mouse E-Cadherin Antigen Affinity-purified Polyclonal Antibody (green; Catalog # AF748) at 10 µg/mL for 3 hours at room temperature. Cells were counterstained with DAPI (blue). B) Paraffin-embedded mouse intestinal tissue stained for Human Cadherin‑17 Antibody (green; Catalog # MAB1032), Human Ki67/MKI67 Antibody (red; Catalog # AF7617), and counterstained with DAPI (blue).

Liver Organoid Formation and Differentiation in Cultrex RGF BME, Type 2. Human Liver organoids were derived from human biopsy tissue. Undifferentiated organoids were formed by embedding dissociated tissue in Cultrex RGF BME, Type 2 and culturing in specialized media. The organoids were differentiated using media containing Recombinant Human FGF-19 (Catalog # 969-FG), DAPT (Catalog # 2634), and Dexamethasone (Catalog # 1126). A) Undifferentiated liver organoids. B) Liver organoids shrink as they differentiate. C) Representative images of differentiated liver organoids expression hepatocyte markers, Albumin and HNF3 beta, as well as E-Cadherin.

Formation of HepG2 Spheroids in Cultrex RGF BME, Type 2. Hepatocyte spheroids were formed by plating HepG2 liver hepatocellular carcinoma cells (10,000 cells per well) in a 24-well plate coated with 5 mg/mL of Cultrex RGF BME, Type 2. Spheroids were cultured for 21 days prior imaging by brightfield microscopy.
