Analysis of adhesion molecules and chemokine receptors. Fluorescence-activated cell scan (FACS) plots of the adhesion molecules and chemokine receptors between the subsets. (A) The isotype control is depicted in the filled line, M0 is the thin black line, the bold black line represents M1, and the grey line M2. (B) Mean fluorescence intensity (MFI) of expression of very late antigen-4 (VLA-4) and platelet endothelial cell adhesion molecule (PECAM/CD31) between the subsets. Chemokine receptor expression using FACS presented in MFI for the different subsets of macrophages. The histogram are representative of three donors and the MFI figures are means and standard error of the mean of three different experiments. CCL, Chemokine C-C motif ligand; CCR, receptor for CCL; CXCL, Chemokine C-X-C motif ligand; CXCR, receptor of CXCL.
