Histological evaluations for inflammatory response of scaffolds at 14 days of subcutaneous implantation, including H&E, CD68, iNOS, and CD206 staining. The scaffolds without GO were labeled “control,” the GO-free scaffolds loaded with 5 × 10⁵ USCs were labeled “U,” the scaffolds containing 0.1% GO were labeled “GO,” and the scaffolds containing 0.1% GO loaded with 5 × 10⁵ USCs were labeled “GO+U.” Scale bar = 200 μm
