Adult Stem Cell-derived Liver Organoids Cultured using Recombinant Human BMP-7 Protein.

Adult stem cell-derived liver organoids were cultured using Cultrex UltiMatrix RGF Basement Membrane Extract (BME001-05) and liver organoid initiation medium, which includes Recombinant Human BMP-7 (Catalog # 354-BP), Recombinant Human HGF (294-HG), Recombinant Human EGF (236-EG), Recombinant Human FGF-10 (345-FG), Recombinant Human Noggin (6057-NG), Recombinant Human R-Spondin 1 (4645-RS), and Recombinant Human Wnt-3a ( 5036-WN), along with the other reagents listed in the liver organoid initiation medium recipe in the human liver organoid culture protocol. After 3 days, liver organoid expansion medium was added for 7-10 days, followed by liver organoid differentiation medium, which includes Recombinant Human BMP-7 (Catalog # 354-BP), Recombinant Human HGF (294-HG), Recombinant Human EGF (236-EG), and Recombinant Human FGF-19 (969-FG), along with the other reagents listed in the liver organoid differentiation medium recipe in the human liver organoid culture protocol. Differentiated human liver organoids were stained using a (A) Mouse Anti-Human Serum Albumin Monoclonal Antibody (MAB1455; red) and a (B) Goat Anti-Human HNF-3beta Antigen Affinity-purified Polyclonal Antibody (AF2400; red) and counterstained with DAPI (5748; blue).

Formulation, Preparation, and Storage

Carrier Free
What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: BMP-7

Bone morphogenetic protein 7 (BMP-7), also known as osteogenic protein 1 (OP-1), is a widely expressed TGF-beta superfamily member with important functions during embryogenesis, in the adult, and in disease (1, 2). Human BMP-7 is synthesized with a 29 amino acid (aa) signal sequence, a 263 aa propeptide, and a 139 aa growth factor domain (3, 4). The growth factor domain of human BMP-7 shares 98% aa sequence identity with mouse and rat BMP-7. The BMP-7 propeptide is cleaved intracellularly but remains in association with the growth factor domain. BMP-7 is subsequently secreted as a tetramer that consists of two propeptides and two disulfide-linked growth factor domains (5, 6). Mature BMP-7 can also form disulfide-linked heterodimers with BMP-2 or BMP-4, complexes that show increased potency and range of activity compared to BMP-7 homodimers (7-9). The presence of the propeptides in the BMP-7 tetramer does not diminish the bioactivity of the growth factor domains (6). Secreted BMP-7 is immobilized in the extracellular matrix as a result of interactions between the propeptide and matrix Fibrillin (5). BMP-7 exerts its biological effects through the type 2 receptors Activin RIIA, Activin RIIB, and BMPR-II and the type 1 receptors Activin RIA, BMPR-IA, and BMPR-IB (2, 6). BMP-7 plays a role in a variety of organ systems. It promotes new bone formation and nephron development (10, 11), inhibits the branching of prostate epithelium (12), and antagonizes epithelial-mesenchymal transition (EMT) (13-15). In pathological conditions, BMP-7 inhibits tumor growth and metastasis (14), ameliorates fibrotic damage in nephritis (13), and promotes neuroregeneration following brain ischemia (16).
