stem cell factor

A glycoprotein cytokine that promotes the differentiation and growth of hematopoietic stem cells into other types of cells.

A gene on chromosome 12q22 that encodes KIT tyrosine kinase receptor ligand, which plays a key role in regulating cellular activities (such as: cell survival and proliferation; haematopoiesis; stem cell maintenance; gametogenesis; mast cell development; migration and function; and in melanogenesis) by activating multiple signalling pathways.

In [S.sub.1]/[S.sub.1d] mice that do not produce membrane-bound stem cell factor, the ligand for kit, small intestinal ICCs at the level of the myenteric plexus are absent, suggesting that the stem cell factor is necessary for their development.[37] The major source of stem cell factor is enteric neurons.
Therefore, the aim of the present study was to study the expression of hematopoietic regulatory molecules including macrophage inflammatory protein (MIP)-1[alpha], tumor necrosis factor (TNF)-[alpha], granulocyte colony-stimulating factor (G-CSF), stromal cell-derived factor (SDF)-1[alpha], stem cell factor (SCF), and transforming growth factor (TGF)-[beta] by BM-MSCs of AA patients.
The proto-oncogene c-kit encodes a 145-kd transmembrane tyrosine kinase receptor (CD117), the ligand of which is stem cell factor (SCF).[13-15] Expression of c-Kit is weak to moderate in a wide variety of normal, benign, and malignant tissues.[16-18] In a subset of mast cell disorders[19] and gastrointestinal stromal cell tumors,[20,21] over-expression has been linked to either an activating or dominant-inactivating c-kit mutation.
On the contrary, other genes did not display significant changes though they code for cytokines or growth factors with a chemoattractant role on different types of stem cells, such as Cxcl12/Sdf1, stem cell factor (SCF), Igf1, Hgf, Pdgfa, and Vegfa.
