PDCM-CB-P grafts enabled stable peri-implant bone regeneration in rabbit tibias. (A–F) Merged images of all test groups showed obvious differences in bone formation. Bar = 1 mm, magnification = 4×. (G,M) Bone regeneration around the implant, as examined by histological analyses, including (H,E), and Masson’s trichrome staining. Bar = 200 μm, magnification = 10×. (H–L, N–R) Similar staining showing much less cancellous bone formation and clear PDCM or fibrous tissues remaining. Bar = 200 μm, magnification = 10×. PDCM, particulate decellularised cartilage matrix; CB, cell brick; P, platelet-rich plasm.
