Objective: To investigate the influence of chemotherapeutic agents and cytokines on growth of bone marrow cells from MT/p210 bcr-ab1 transgenic mice.Methods: The bone marrow cells of transgenic chronic myelogenous leukemia (CML) model mice carrying metallothionein (MT) promoter/enhancer, bcr-abl (p210)cDNA and SV40 splicing/poly (A) signal sequences were cultured in liquid and soft agar with hydroxyurea (Hu),5-fluorouracil (5-Fu), mouse stem cell factor (mSCF)and mouse interleukin-3 (mIL-3) independently or collectively. The cells and colonies were counted. The levels of transgene expression were detected by reverse transcriptase-polymerase chain reaction (RT-PCR).Results: The cell proliferation, colony formation and transgene expression of the bone marrow cells were stimulated with mSCF and mIL-3, but there was little growth without any growth factors, or when mSCF,mIL-3 and Hu or 5-Fu were added. Conclusion: The combined utilization of chemotherapeutants and cytokines is a potentially effective strategy of clinical treatment for CML.
