Abstract：Objective: To investigate the effect of macrophage cell line RAW264.7 on the migration and expression of TGF-β1, IL-6 and MCP-1 gene level of mouse bone marrow derived mesenchymal stem cells(MSCs) under the stimulation of lipopolysaccharide(LPS). Methods： Adherent method was used to isolate mouse bone marrow mesenchymal stem cells. MSCs were co-cultured with RAW264.7 through transwell assay. Co-culture experiments were divided into four groups: culture medium control, RAW264.7 cells, LPS and RAW264.7 cells stimulated by LPS. Cell transwell migration assay were performed to detect the number of migrated MSCs under the four different conditions. At the same time, qRT-PCR was performed for the quantification of TGF-β1, IL-6 and MCP-1genes. Results： RAW264.7 expressed high level of TNF-α, IL-6, IL-1β and MCP-1 gene by LPS stimulation. In the presence of RAW264.7, the migrated MSCs numbers were higher than controls(P<0.01), while RAW264.7 cells remarkably increased the migratory ability of MSCs under the stimulation of LPS(P<0.01). Meanwhile, the expression of TGF-β1, IL-6 and MCP-1 genes were enhanced by co-culture with RAW264.7 in the presence of LPS(P<0.05). Conclusion： Macrophage cell line RAW264.7 enhanced the migratory ability and exchanged the cytokine expression of MSCs under the stimulation of LPS, which provided mechanistic insights into the recruitment of MSCs in inflammation.
