Stem cell factor (SCF)/c‐kit system is critical for human mast cell development. We thus examined the effects of STI571, an inhibitor of the c‐kit tyrosine kinase receptor, on the proliferation and function of human mast cells. STI571 at concentrations of 10−6 M or higher almost completely abolished the SCF‐dependent progeny generation from cord blood‐derived cultured mast cells through an inhibition of the tyrosine phosphorylation of c‐kit. The compound also suppressed the early phase of mast cell development. The extinction of mast cell growth induced by STI571 may be due largely to apoptosis according to the flow cytometric analysis and gel electrophoresis. Two‐hour exposure to STI571 that failed to influence the total viable cell number suppressed adhesion of the cells to fibronectin in the presence of SCF without altering the expressions of integrin molecules. Our results may provide a fundamental insight for the clinical application of STI571 in allergic disorders.
