Stem cell factor (SCF), otherwise known as KIT ligand or Steel factor1 is a paracrine regulator of germ cell development.2 SCF has the ability to stimulate the growth of hematopoietic progenitor cells and to generate colony-forming cells (CFC) from highly enriched populations of hematopoietic cells.3 SCF is produced by the Sertoli cells and involved in the local regulation of spermatogenesis4 and liver regeneration.5 SCF in conjunction with interleukin-31 may play a significant role in airway remodeling by promoting the recruitment of bone marrow-derived fibroblast precursors into the lung with the capacity to promote lung myofibroblast differentiation.6
>97% by SDS-PAGE and analyzed by silver stain.
<0.1 EU/µg as determined by the LAL method
The biological activity of Mouse SCF was determined by a cell proliferation assay using a human factor-dependent cell line, TF-1 (Kitamura, T. et al., 1989, J. Cell Physiol. 140:323 - 334). The expected ED50 for this effect is typically 2.5-10 ng/ml. The cell number is assessed in a fluorometric assay using the redox sensitive dye, Resazurin.
