Human fibroblast growth factor 4 (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. Recombinant FGF-4 is an important component of cardiac, intestinal and other organoid culture media.
