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

Figure 1

Anteroposterior radiographic images at 10 weeks following endothelial progenitor cell (EPC) implantation into the defect site. Control refers to the animals that received no 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.
