Serrate/Jagged and Delta are cell surface ligands for Notch receptors that may influence hematopoietic cell fate decisions and are known to be expressed in bone marrow stromal cells. In a series of screenings of cDNAs constructed by a cDNA library subtraction technique, we identified Jagged1, one of the Notch ligands, as a gene up-regulated by macrophage colony-stimulating factor (M-CSF) in bone marrow macrophages. Therefore, we compared stromal cells and macrophages for expression of Notch ligands including Jagged1 and analyzed the regulation of their expression by cytokines.
