Kinetics of appearance of c-Fms⁺ and Mac-1⁺ peritoneal cells. At various times after TM injection, peritoneal cells were monitored for c-Fms (•) and Mac-1 (○) expression by flow cytometry (see the Materials and Methods). Data are the mean values ± SEM from 3 experiments (8 mice/time point/per experiment). A partial kinetic analysis was also performed another 8 times. When error bars are not presented, the errors are smaller than the size of the symbols.
