The stimulatory activity of cells generated from TNF/LTα/LTβ−/− BM culture is significantly reduced compared with that from wt BM culture.
BM cells (1 × 106 cells/mL) from either wt (●) or TNF/LTα/LTβ−/− (○) mice were cultured with GM-CSF and IL-4 for 9 days. Cells were collected on day 9 and subjected to 30 Gy irradiation. Indicated number of generated cells were cocultured with syngeneic (A) or allogeneic (B) LN cells (1 × 106 cells/mL) for 4 days. During the last 18 hours of the culture, [3H]dThd was added in each well. The values are the means ± SD of quadruplicate wells. Data from 1 of 3 representative experiments are shown. *P < .01 compared with TNF/LTα/LTβ−/− BM culture. CPM indicates counts per minute.
