Abstract 5010 This study was aimed to investigate the mRNA expression levels of hepatocyte growth factor(HGF), stromal-derived factor-1(SDF-1), Chemokine (C-C motif) ligand 2 (CCL2) and interleukin-8(IL-8) in bone marrow mesenchymal stem cells (MSC) from multiple myeloma (MM) patients. The real time quantitative polymerase chain reaction(RQ-PCR)technique was used to detect the mRAN expression levels of HGF, SDF-1, CCL2 and IL-8 in bone marrow MSC from 20 newly diagnosed MM patients compared with 9 controls. The results indicated that the mean mRNA expression level of HGF was up-regulated in MM patients, as compared with control (P < 0.01). However, the mean mRNA expression level of SDF-1 mRNA was down-regulated in MM patients, as compared with control (P < 0.05). There was no significant difference in the mRNA expression levels of CCL2 and IL-8 between MM and control cohorts (P > 0.05). The research suggests that multiple chemotaxis-related factors expression of bone marrow microenvironment cellular component are dysrelugulated in MM patients, which might result from the interplay between MM cell and MSC. No relevant conflicts of interest to declare.
