IFNG and neoplasm: To observe the in vitro effect of BMSCs on CD3+IFNγ+ T cells, 5 × 105 peripheral blood white cells obtained from C57 and BALb/c mice were co-cultured with 1 × 105 NIH-3T3 or syngeneic BMSCs in 60% v/v tumor supernatant culture medium with or without the presence of 1 × 105 bone marrow suspension cells (MDSCs) obtained from femurs and tibias of C57 and BALb/c mice.
