“…IM-9 (human B-lymphoblastoid), Jurkat (human T-lymphocyte), THP-1 (human acute monocytic leukemia), and HL-60 (human acute promyelocytic leukemia) cell lines were cultured in RPMI 1640 medium supplemented with 10% (v/v) fetal bovine serum. Mouse NK cells were isolated from spleen of Runx3-deficient (19) and wild type mice by negative selection (R&D MagCollect mouse NK cell isolation kit, MAGM210) and cultured for 7 days in RPMI 1640 medium containing 10% (v/v) fetal calf serum, 2 mM L-glutamine, 1% sodium pyruvate, 1% nonessential amino acids, 50 M 2-mercaptoethanol, and 1000 units/ml IL2 (Biological Industries, Beit-Haemek, Israel, 30-T209B). All cultures were supplemented with 100 units/ml penicillin, 100 units/ml streptomycin.…”
