OBJECTIVE To produce and examine decellularized kidney scaffolds from porcine as a platform for kidney regeneration research. METHODS Porcine kidneys were decellularized with sodium dodecyl sulfate solution and Triton X-100 after the blood was rinsed. Then the renal ECM scaffolds were examined for vascular imaging, histology to investigate the vascular patency, degree of decellularization. RESULTS Renal ECM scaffolds of porcine kidneys were successfully produced. Decellularized renal scaffolds retained intact microarchitecture including the renal vasculature and essential extracellular matrix components. CONCLUSION We have developed an excellent decellularization method that can be used in large organs. These scaffolds maintain their basic components, and show intact vasculature system. This represents a step toward development of a transplantable organ using tissue engineering techniques.
