Abstract
We established a quantitative analysis system for 4.0 kb and 1.6 kb macrophage colony-stimulating factor (M-CSF) mRNA, using reverse transcription-polymerase chain reaction. Using this system, we performed quantitative analysis of the two mRNAs expressed in the human stromal cell line, KM102, in the resting condition and when stimulated by various concentrations of interferon-γ (IFN-γ). The expression of 1.6 kb M-CSF mRNA was more efficiently stimulated by IFN-γ than that of 4.0 kb M-CSF mRNA. The alternative splicing of a single M-CSF gene has been shown to generate several M-CSF proteins with different localization; we believe that molecular analysis of the transcription products by this system is important to better understand the physiological significance of the different species of M-CSF derived from each mRNA.
