Fig. 2. hUC-MSCs reduced M1 polarization in femoral heads. (A) The CD86 and F4/80 of macrophages were stained using immunofluorescence assay (magnification, x400). Scale bar: 20 μm. (B) The CD206 and F4/80 of macrophages were stained using immunofluorescence assay (magnification, x400). Scale bar: 20 μm. The means±SD of six independent samples were shown. *p<0.05 and **p< 0.01, compared with control group; ^##p<0.01, compared with model group.
