Effect of IL-10 on preB cell colony formation. A total of 100,000 unfractionated bone marrow cells were plated in 0.9% methylcellulose in the presence of IL-7 and/or IL-10. After 7 days of incubation at 37°C, 5% CO2 in air, preB cell colonies were counted. Results represent the mean ± SEM of three independent experiments with duplicate dishes for each group in each experiment. * P < .05, as compared with IL-7 alone.
