Images of CD68, iNOS, CD206, and CD31 staining of specimens after 12 weeks of scaffold implantation. 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. Red arrows represent new vessels
