Effect of BCP on DNA synthesis in BMMs in the presence of CSF-1. BMMs from which CSF-1 had just been removed were cultured in RPMI/10%FBS in the presence of increasing concentrations of CSF-1, in either the absence (○) or the presence (◎) of BCP (100 μg/ml). After one day, cells were washed twice to remove BCP, recultured again in the increasing CSF-1 concentrations, and pulsed with [³H]TdR for a further two days. Data are mean values ± SEM from triplicate cultures and are from a representative experiment that was repeated seven times.
