Immunocytochemistry staining of macrophages suggests that modified alginates alter phenotype: (A) nitro/epoxide; and (B) ester/amide modified alginates were coated on cells; and (C) cells in the absence of alginate are shown for comparison. Cells were stained with fluorescently labeled CD206 (red, M2 marker) and CD11c (green, M1 marker) markers as well as DAPI (blue). Scale bar is 50 μm.
