Objective To observe the effect of the human umbilical cord blood-derived stromal cells (hUCBDSCs) and multiple myeloma bone marrow stromal cells (MM BMSCs) on the biological characteristics of KM3 cells. Methods After KM3 cells were co-cultured with hUCBDSCs or MM BMSCs
the proliferation
cell cycle and the apoptotic rate were determined by growth curve plotting and flow cytometry respectively. Real-time Q-PCR was used to mea
sure the mRNA expressions of Bcl-2 and Bax. Results As compared with MM BMSCs
hUCBDSCs markedly suppressed the proliferation of the KM3 cells. KM3 cells in the KM3/MM-BMSCs co-culture group were arrested in G

while KM3 cells in the KM3/hUCBDSCs co-culture group predominantly in S phrase. The apoptotic rate of KM3 cells in the KM3/ hUCBDSC co-culture group were higher than that in the KM3/MM-BMSCs co-culture group. Conclusion In comparison with MM BMSCs
hUCBDSCs inhibit the proliferation of KM3 cells and promote the apoptosis.
