Hu Recom FGF-7 (KGF), 10 µg

Recombinant human FGF-7 (also known as Keratinocyte Growth Factor, KGF) from STEMCELL Technologies is supplied as a 10 µg vial for use in epithelial cell culture and organoid research. This growth factor selectively activates FGFR2b on epithelial cells, supporting proliferation of keratinocytes, intestinal epithelial cells, and other epithelial lineages. Researchers commonly reconstitute the powder in sterile PBS with 0.1% BSA and aliquot before freezing at -20 degrees C to preserve activity across multiple experiments. Working concentrations typically range from 5 to 50 ng/mL depending on the cell system, with documented roles in lung organoid maintenance, skin tissue engineering, and regenerative medicine studies. Each vial is intended for research use only in vitro applications, including expansion of primary epithelial cultures and differentiation of pluripotent stem cells toward airway or intestinal fates.
