Gene Information

General description

Stem cell factor (SCF), also known as the c-kit ligand, is produced by the gastrointestinal smooth muscle cells, enteric neurons, endothelial cell, lung fibroblast and bone marrow adipocytes. The SCF gene is mapped to murine chromosome 10.
Recombinant mouse stem cell factor (SCF) is a 18.3 kDa protein containing 164 amino acid residues.


SCF, also known as c-Kit ligand (KL), steel factor (SLF) and mast cell growth factor (MGF), is a 30 kDa glycoprotein with broad activities on various tissues, including hematopoietic cells, pigment cells, and primordial germ cells. SCF is secreted by endothelial cells, fibroblasts, and bone marrow stromal cells as a membrane-bound form which may be cleaved to release the soluble form. Both forms are active in promoting colony formation from murine bone marrow cells, but membrane-bound SCF is more effective in promoting hematopoieses in vivo, suggesting a role in cellular interactions between hematopoietic and stromal cells. The soluble is thought to exist in solution as a noncovalently linked dimer. SCF is structurally related to M-CSF (CSF-1) and Flt-3/Flk-2 Ligand (FL) with all three sharing a similar size, existence of transmembrane and soluble forms, four conserved cysteines, and alternative splicing exon locations, but they share little sequence homology. SCF alone is a modest colony stimulating factor. However, in the presence of other cytokines such as EPO, TPO, GM-CSF, G-CSF, M-CSF, IL-3, and IL-7, SCF is a potent costimulant that works synergistically to increase the size of myeloid, erythroid or lymphoid lineage colonies without influencing the lineage differentiation of the progenitors.
Stem Cell Factor from mouse has been used in the evaluation of in vitro 5-lipoxygenase inhibition by measuring the formation of LTC4.

Biochem/physiol Actions

Stem cell factor is responsible for cellular development, proliferation, migration and survival, specially observed with cardiac stem cells. This phenomenon is mediated by stem cell factor (SCF) through chemotaxis. SCF is involved in repair mechanism of myocardial infarctions. SCF signalling is responsible for the function and survival rate of interstitial cells of Cajal. Decreased level of SCF leads to gastrointestinal motility disorders. SCF might be associated with systemic vascular remodeling. SCF signalling is also believed to contribute to the pathogenesis of pulmonary hypertension.
