Bone marrow cells were isolated from femur and tibia of C57/BL6 mice and were cultured in L929 fibroblast conditioned RPMI 1640 medium (containing 15% L929 supernatant and 10% FCS) for 7 days. The resulting macrophages were stimulated over night with 20 MOI of live Hh. Cells were pre-incubated with DATS (10 µM) 30 min before the stimulation with Hh. Then, the supernatants were collected for the detection of IL-6 and TNFα cytokines by ELISA.
