Recombinant human FGF-4 protein (Qk004)
Human FGF-4 protein is used for the proliferation and differentiation of embryonic and induced-pluripotent and tissue (mesenchymal) stem cells and promotes neural stem cell proliferation. FGF-4 is an important component of cardiac, intestinal and other organoid culture media.
High purity and bioactivity 14 kDa non-glycosylated, bioactive domain of human fibroblast growth factor 4, animal-derived component free (ACDF) and carrier-protein free (CF).
FGF4 induces cell proliferation of iPSC cells (Stemnovate iPSC1 line). Data from Qk004 lot #010
IPSC (Stemnovate iPSC1) were cultured in serum-free media containing 100ng/ml hFGF4. The number of viable metabolically active cells was detected by ATP measurement using a bioluminescent reaction (n=3; data show mean ± SEM). No media change was performed on day 2 leading to reduced viable cell numbers on day 3. Data provided by Stemnovate Ltd, Cambridge, UK.
FGF-4 protein induces proliferation of HEK293T cells.
Recombinant human FGF4 protein migrates as a single band at 14 kDa in non-reducing conditions (NR) and upon reduction (R). No contaminating protein bands are visible.
Purified recombinant protein (7 µg) was resolved using 15% w/v SDS-PAGE in reduced (+β-mercaptothanol, R) and non-reduced conditions (NR) and stained with Coomassie Brilliant Blue R250.

We are a company founded and run by scientists to provide a service and support innovation in stem cell biology and regenerative medicine. All our products are exceptionally high purity, with complete characterisation and bioactivity analysis on every lot.
Fibroblast growth factor 4 (FGF4) is a member of the FGF superfamily with a physiological role in the regulation of proliferation and differentiation in embryonic stem cells and tissue stem cells1-3.
Recombinant human FGF4 protein promotes neural stem cell proliferation and neuronal differentiation in the postnatal brain4, increases the proliferation rate of human adult bone-marrow derived mesenchymal stem cells5 and supports the maintenance, proliferation and self-renewal properties of human embryonic stem cells6.
Synergism between FGF4 and WNT signalling acts to form hindgut organoids from iPSC-derived human posterior gut endoderm cells7 and recombinant human FGF4 protein is used to mimic embryonic intestinal development during directed differentiation in culture of pluripotent stem cells into intestinal organoids.
