Fig. 5From: Escherichia coli-derived recombinant human bone morphogenetic protein-2 combined with bone marrow-derived mesenchymal stromal cells improves bone regeneration in canine segmental ulnar defectsHistology of the regenerated bone. a–f Representative histological sections of the regenerated bone at 12 weeks after surgery stained with hematoxylin and eosin (×400, scalebar = 100 μm). The groups treated with 560 μg rhBMP-2 with 107 (a), 105 (b), and 0 (c) cells, and 140 μg rhBMP-2 with 107 (d), 105 (e), and 0 (f) cells are shown. Scale bar: 500 μm. g Numbers of osteocyte-like cells per trabecular bone area. The numbers of osteocyte-like cells in the trabecular bone (mean ± SD) are shown. The numbers of osteocyte-like cells are significantly increased by transplantation with BMSCs. *P < 0.05Back to article page
