Fibroblast Growth Factor (FGF) — frequently asked
What are fibroblast growth factors?
FGFs are a family of related signalling proteins that activate the FGFR tyrosine kinase receptors. They include classical heparin-binding members such as FGF1 and FGF2 and endocrine members such as FGF19, FGF21 and FGF23.
Why is FGF2 used in cell culture?
Recombinant FGF2, also called basic FGF, is a common supplement for maintaining stem and progenitor cell populations in vitro. It is reported to support proliferation while limiting spontaneous differentiation, so it is frequently included in defined culture media.
How do FGF-derived peptides differ from recombinant FGF?
Short peptides correspond to selected regions of the parent protein rather than the folded molecule. They are used to test which sequence segments contribute to receptor contact or antibody recognition, and generally do not reproduce full protein activity.
