Adult stem cell-derived Lung Organoids Cultured using Recombinant Human FGF-10 Protein.

Adult stem cells isolated from human lung biopsy tissue were embedded in Cultrex UltiMatrix RGF Basement Membrane Extract (BME001-05) and cultured for 20-60 days in lung organoid expansion medium, which includes Recombinant Human FGF-10 (Catalog # 345-FG), Recombinant Human KGF/FGF-7 (251-KG), Recombinant Human Noggin (6057-NG), and Recombinant Human R-Spondin 1 (4645-RS), along with the other reagents listed in the lung organoid expansion medium recipe in the lung organoid culture protocol. Lung organoids were able to differentiate and exhibit markers for various cell types of the lung. Lung organoids were stained with (A) a Rabbit Anti-Human Cytokeratin 5 (KRT5) Monoclonal Antibody (Novus Biologicals, Catalog # NB110-56916; green) and a Goat Anti-Human p63/TP73L Polyclonal Antibody (AF1916; red) to visualize basal cells, (B) a Hamster Anti-Mouse Podoplanin (PDPN) Monoclonal Antibody (Novus Biologicals, Catalog # NB600-1015; green) to visualize alveolar type I cells and a Goat Anti-Human p63/TP73L Polyclonal Antibody (AF1916; red) to visualize basal cells, and (C, D) a Mouse Anti-MUC5AC Monoclonal Antibody (Novus Biologicals, Catalog # NBP2-15196; green) to visualize Goblet cells and a Mouse Anti-Human/Mouse/Rat SOX2 Monoclonal Antibody (MAB2018; red). All samples were 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: FGF-10

The Fibroblast Growth Factors (FGFs) are heparin binding glycoproteins that exert a variety of biological activities toward cells of mesenchymal, neuronal, and epithelial origin. FGF-10 belongs to the subgroup of FGFs that also includes FGF-3, -7, and -22 (1). Mature human FGF-10 is an approximately 20 kDa protein that contains a serine-rich region near its N-terminus (2, 3). It shares 93% and 96% amino acid sequence identity with mouse and rat FGF-10, respectively. FGF-10 is secreted by mesenchymal cells and associates with extracellular FGF-BP (1, 4). It preferentially binds and activates epithelial cell FGF R2 (IIIb) and interacts more weakly with FGF R1 (IIIb) (5). The mitogenic and chemotactic properties of FGF-10 are critical in many tissues during embryogenesis. This includes limb bud initiation (6), palate development (7), branching morphogenesis and directional outgrowth of lung buds (8, 9), formation of the otic vesicle and chochlea (10), adipogenesis (11), and the development of prostate, mammary, lacrimal, and submandibular salivary glands (12 - 15). FGF R2 (IIIb) signaling in these responsive tissues is similarly important during embryogenesis (7, 10, 13 ‑ 15). The expression and function of FGF-10 are negatively regulated by Shh and BMP-4 in the developing lung (8, 9). Overlapping expression patterns and activities with FGF-3, -7,  and -8 suggest at least a partial redundancy in FGF‑10 biology (7, 10, 14, 15). FGF-10 induced signaling through FGF R2 (IIIb) also contributes to the progression of pancreatic cancer (16).
