Figure 4

Human PBMC were allowed to migrate for the indicated times through human cardiac microvascular endothelium in response to MCP-1 and thereafter adhered to poly d-lysine coated coverslips. The cells were stained for the external markers CD86, CD206, and CD301, and after fixation and permeabilization, for the internal markers NOS2 and prolylhydroxylase (labeled prolylhyase in the figure). DAPI was used to stain cell nuclei blue. The insets are cells at either higher magnification (CD301) or cells with external staining and an internal marker (CD86 plus NOS2 and CD206 plus prolylhydroxylase) with white arrows extending from the label. The white arrow within the center panel indicates a CD86 positive cell in the low magnification field, and the inset at top right shows a cell that is double positive for CD86 and CD206. White bars represent 20 μm.
