Apigenin promoted macrophage M2 polarization. Above are representative immunofluorescence pictures of CD206 (magnification, ×100), The blue fluorescence is DAPI and the red fluorescence is CD206. Compared with that in group N, the CD206 MFI in the IL-4 treatment group was significantly increased, and the CD206 level in the IL-4 + API group was further increased. The lower figure shows the quantitative fluorescence intensity of CD206-positive cells: ## p < 0.01 versus the IL-4 group.
