title: [Influence of chemotherapeutants and cytokines on growth and transgene expression of bone marrow cells from MT/p210(bcr-abl) transgenic mice].
abstract: The bone marrow cells of CML(chronic myelogenous leukemia) transgenic 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 combinatively. The cell or colony counting and transgene RT-PCR analysis showed that the proliferation, colony formation and transgene expression of the bone marrow cells were advanced in the combinative culture of mSCF with mIL-3, but they were significantly inhibited in the culture without any growth factors, or with mSCF, mIL-3 and Hu or 5-Fu. These findings suggest that the combinative utilization of chemotherapeutants and cytokines is a potentially effective strategy of the clinical treatment for CML.
