Immunohistochemistry staining was employed to detect the expression of OCN in the bone defect area. The black arrowheads indicate OCN-positive osteoblasts at the MBCP–new bone interface. The red arrows indicate a high expression region and OCN-positive osteocytes embedded within the bone and connective tissue matrix. Scale bar = 100 μm. (NB new bone, CT connective tissue, BM bone marrow, MBCP scaffold, DPSCs dental pulp mesenchymal stem cells, Mel melatonin, OCN osteocalcin)
