This communication summarizes the procedures that enabled isolation of adult murine thymic stromal cell lines that naturally express Notch ligands Jagged-1 or Delta-1. Histochemical characterization of these cell lines, in terms of ligand and cell type, revealed epithelial cells that bear an antigen characteristic of the thymic medulla and express either Jagged-1 or Delta-1. FACS sorting of stromal cells that naturally express these and other ligands is thus feasible, and such cells can be used to investigate the activity of each ligand in Notch-mediated commitment to the T-lymphocyte pathway.
