Delta-Like-1 Changes the Immunomodulatory Property of OP9 Cells

Figure 6

NO production in OP9 and OP9DL1 cells in the presence of different stimulators. OP9 and OP9DL1 were stimulated with TNFα/IFNγ (each 2 ng/mL), LPS (10 μg/mL)/IL4 (25 ng/mL), or PMA (50 ng/mL)/ion (1 μg/mL) for 24 h, respectively. Supernatants were collected at 6, 12, and 24 h and used for NO assay, respectively.
