Figure 4: MCP-1, but not G-CSF served as a chemoattractant for human monocytes (THP-1 cell line). (A) Migration of monocytes was not elicited by G-CSF at various concentrations (G-CSF added to lower wells of migration assay) (n=6 wells per concentration). (B)MCP-1 stimulated cell migration in a concentration-dependent manner through a 5 μm fibronectin coated filter over a 2 h period (One-way ANOVA p<0.0001). |
