Proliferation of MO7e cells in response to SCF correlates with c-kit receptor dimerization detected by FRET. MO7e cells were washed to remove GM-CSF and resuspended at a concentration of 1 × 105 cells/mL in IMDM suppplemented with 10% FCS and various concentrations of SCF (0 to 1,000 ng/mL; •), or 104D2 (0.5 μg/mL). After a 3-day incubation at 37°C, the number of viable cells was counted. The data represent the mean (± standard error of mean [SEM]) of triplicate values from one experiment. The wells supplemented with 104D2 contained 1.1 ± 0.2 × 105 MO7e cells/mL on day 3.
