Images of CD206 immunofluorescence staining of macrophages co-cultured with each scaffold for 48 h. Scale bar = 100 μm. The scaffolds without GO were labeled “control,” the GO-free scaffolds loaded with 1.5 × 10⁵ USCs were labeled “U,” the scaffolds containing 0.1% GO were labeled “GO,” and the scaffolds containing 0.1% GO loaded with 1.5 × 10⁵ USCs were labeled “GO+U.” Macrophages cultured with the induction medium for M2-type macrophages were used as a positive control (+), and macrophages cultured with only culture medium were labeled “Blank”
