Figure 2. Flow cytometric analysis of M1 and M2 macrophage markers in cultures of HBCs.
HBCs were stained for CD11b (A), CD40 (B), CD163 (C), and FR-β (D) and analyzed by flow cytometry indicated by the solid line in each panel. The dashed line in each panel represents the signal obtained using an isotype-matched control antibody. The results are representative of three independent experiments.
