Figure 1 Micro-computed tomography imaging at 2 wk post-fracture. A: Rats were injected with normal saline; B: Rats were injected with 2.5 × 106 mesenchymal stem cells (MSCs); C: Rats were injected with 5.0 × 106 MSCs; D: Rats were injected with 10.0 × 106 MSCs. Callus formation was observed in all groups; however, fracture lines (arrows) were clearly observed, indicating that union had not yet occurred.
