Delayed Endothelial Progenitor Cell Therapy Promotes Bone Defect Repair in a Clinically Relevant Rat Model

Figure 5

Treatment of bone defects with EPCs increases biomechanical strength and stiffness. Torsional testing revealed that EPC treatment, either in an acute or delayed fashion, increased ultimate torque and torsional stiffness compared to the respective control groups. For both ultimate torque and torsional stiffness, no differences were observed between acute and delayed treatment with EPCs. denotes significant difference between groups ().
