ABSTRACT Cytokines have pleiotropic regulatory effects on hematopoietic cells and many other cell types that participate in host defence and repair processes. Granulocyte-macrophage colony-stimulating factor GM-CSF mediates the growth and differentiation of granulocytes and macrophages and regulates the biological functions expressed by mature cells of these lineages. Stem cell factor SCF is a multifunctional cytokine involved in hematopoiesis melanogenesis and gametogenesis. In order to determine the complementary DNA cDNA of canine GM-CSF and canine SCF cDNA clones were generated from lipopolysaccharide IPS stimulated peripheral blood mononuclear cells PBMCs and bone marrow cells by reverse transcription PCR amplification. The canine GM-CSF cDNA obtained in this study contains an open reading frame encoding 144 amino acid residues and has 53-75 homology with those of human cat sheep pig cow and mouse. Canine SCF cDNA consist of an open reading frame encoding 274 amino acid residues and shares 81-92 homology with those of human cat pig cow and mouse.
