Recombinant Murine KIT LigandKitI, KL-1Stem Cell Factor, SCF Mast Cell Growth Factor, MGF

C-kit ligand, the recently identified ligand for the kit tyrosine kinase receptor, is mapped to the mouse S1 locus. This pleiotropic cytokine, alternately known as stem cell factor (SCF), mast cell growth factor (MGF) and steel-factor (SLF), plays essential roles in gametogenesis, melanogenesis and early stages of hematopoiesis. In vitro and in vivo, KITLG can stimulate the proliferation of mature, as well as the proliferation and maturation of immature, mast cells. KITLG acts in a synergistic manner on purified primitive human and mouse hematopoietic precursors, with various growth factors (such as IL1, IL3, IL6, IL7, and Epo), to induce myeloid, erythroid and lymphoid lineage colony formation. The finding that KITLG is also expressed in the nervous system suggests a possible role for KITLG in the development of the nervous system.
