Endothelial Progenitor Cell Therapy for Fracture Healing: A Dose-Response Study in a Rat Femoral Defect Model

Figure 5

3D reconstruction of a representative femur from each group created based on micro-computed tomography data. For each representative femur, the image on the left provide an outside view of the bone, and the image on the right show the bone midsection. Control refers to the animals that received no endothelial progenitor cells (EPCs); 0.1 M, 0.5 M, 1.0 M, 2.0 M, and 4.0 M refer to the animals that received 1 × 10⁵, 5 × 10⁵, 1 × 10⁶, 2 × 10⁶, and 4 × 10⁶ EPCs, respectively. Contralateral refers to the non-operated, contralateral femur.
