Hematoxylin & eosin (H&E) stained images of the hDBM/DBM/pTCP and hDBM/DBM/gTCP bone grafts in the femur defect model at 1 month and 2 months after implantation. Images showed the DBM with empty lacunae in hDBM/DBM/pTCP (a, b) and hDBM/DBM/gTCP (c, d) grafts implanted areas at 1 month. After 2 months implantation of hDBM/DBM/pTCP (e, f) and hDBM/DBM/gTCP (g, h) grafts showed fibrous dysplasia-like structures and bone formation, respectively. (scale bar: low magnification = 200 μm; high magnification = 50 μm) (arrows, empty lacunae; arrow heads, osteocyte; star, degraded gTCP; blue arrows, resorbed DBM; red arrows, osteoblast).
