Fig. 12From: Graphene oxide-modified silk fibroin/nanohydroxyapatite scaffold loaded with urine-derived stem cells for immunomodulation and bone regenerationImages 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.
