Human Urine-Derived Stem Cells: Potential for Cell-Based Therapy of Cartilage Defects

Figure 1

The process of the establishment of cartilage defect model. (a) General disinfection of the knee. (b) An incision was made on the medial joint of the knee. (c, d) After the joint capsule was opened, the patella was dislocated laterally and exposed femoral condyles. (e) A corneal trephine with a diameter of 5 mm was used to outline the cartilage defect site. (f) Wound closure.
