Recombinant Human FGF-4 Cold Storage & Freezers use a 4-parameter logistic (4-PL)Description FGF 4 (Fibroblast Growth Factor 4), a member of the FGF family, is a secreted glycoprotein that activates downstream signaling pathways (such as MAPK and PI3K AKT) by binding to its receptors (FGFRs). It promotes cell proliferation, differentiation, migration, and survival, playing a central role in embryonic development, mesoderm formation, and stem cell maintenance. In stem cells, it helps maintain pluripotency; for example, FGF 4 and
