ABSTRACT
Objective To investigate the expression and significance of transforming growth factor-β1 (TGF-β1) gene in bone marrow mesenchymal stem cell (BMMSC) derived from patients with multiple myeloma (MM).Methods BMMSC of 7 MM patients and 10 patients with iron deficiency anemia were cultured in vitro.The morphology of BMMSC was observed and the growth curve was portrayed according to the daily results of BMMSC proliferation.Total RNA was extracted from BMMSCs and transcription of TGF-β1 gene in BMMSC was measured by reverse transcription-PCR.Results The proliferative activity of BMMSC was not significantly different between the two groups,but expression of TGF-β1 gene of BMMSC was higher in MM patients (0.01241±0.00419) than the control group (0.00122±0.00030) (t =3.218,P < 0.05).Conclusion The abnormally high expression of TGF-β31 gene in BMMSCs could contribute to the pathogenesis of MM.
