Additional file 1 of Monocyte Chemoattractant Protein-1 promotes cancer cell migration via c-Raf/MAPK/AP-1 pathway and MMP-9 production in osteosarcoma

Additional file 1: Figure S1. Expression levels of MMP9 and CCR4 in migration-prone subclones of MG63 osteosarcoma cells, osteosarcoma cell lines and normal osteoblasts. Figure S2. MPC-1 contributes to MMP-9 expression in osteosarcoma cell lines. Figure S3. MCP-1 promotes osteosarcoma cells migration through CCR2, c-Raf, MAPK and AP-1 signal pathways
