THP-1 cell line differentiated into M2-type macrophages. (A) Expressions of CD68 and CD206 in M2-type macrophages by flow cytometry. M2-type macrophage phenotypes CD68 and CD206 were highly expressed in M2-type macrophages; (B) Expression of CD206 in M2-type macrophages by direct immunofluorescence assay: (a,b) M2-type macrophage phenotypes CD206 was highly expressed in M2-type macrophages by fluorescence microscope and ordinary light filming (×400). (c,d) THP-1 cell line did not express CD206 by fluorescence microscope and ordinary light filming (×400).
