TF-1 cells were deprived of growth factor for 24 hours and then stimulated with 2 ng/mL GM-CSF for 0 to 24 hours. Whole cell lysates were prepared from five experiments and protein from an equivalent cell number was loaded on each lane. Immunoblotting was performed as described in Materials and Methods. The densities of bands were measured with a Molecular Dynamics Densitometer and Quantity One Software, and the mean ± SEM is shown.
Significant increase in response to growth factor stimulation (P < .05).
