Treatment	Cell population	Mean ± SE no. of cpm (103)b	% Inhibitionc
Expt 1
Diluent	Adherent	29.5 ± 1.4
	Nonadherent	49.7 ± 7.7
rmGM-CSF	Adherent	37.9 ± 2.6	−28

^aMice were treated with 50 μg of rmGM-CSF/kg/day or an equal volume of diluent for 1 week, and lung leukocytes were harvested. 

^bMean cpm of [³H]leucine incorporation of triplicate or quadruplicate wells. 

^cPercent inhibition calculated as [1 − (experimental/control)] × 100.
