Effect of SCF on ceramide generation in irradiated Ba/F3-Kit cells.
Cells were prelabeled with [3H]palmitate for 48 hours. Cells were then washed, treated (○) or not (●) with SCF (200 ng/mL for 30 minutes), and irradiated at 4 Gy. Following incubation during the indicated times, aliquots (3 × 106 cells/mL) were collected and lipids were extracted. Labeled ceramide was resolved by thin-layer chromatography and identified as described in “Materials and methods.” Results are the mean ± SD of 3 independent experiments (*P < .05).
