Decellularization has been explored as a powerful technique for the reconstruction of three-dimensional organ structures.
Recent advances in bioengineering have established an organ regeneration-based infrastructure as an alternative to organ transplantation. The successful implementation of these approaches will help to reduce medical costs and improve prognosis, productivity, and quality of life for patients with renal diseases. Thus, the development of transplantable kidney and nephron regeneration technologies is required. Moreover, acute graft rejection and failure have not been overcome by transplantation. Although renal transplantation is curative for individuals with ESRD, the number of recipients awaiting transplantation exceeds the availability of organ donors. Therefore, dialysis does not ensure the long-term survival of patients with ESRD 6. In addition, since dialysis creates a financial burden for many patients, it may not be economically feasible 5. While dialysis may compensate for impaired renal functions, it involves extracorporeal circulation, which entails risks of thrombosis and infection 5. Currently, available treatment options for ESRD are limited to dialysis and transplantation. Thus, such chronic kidney diseases progress to end-stage renal diseases (ESRD). Kidney failure is defined as the loss of nephron functions, such as reduced glomerular filtration rate and increased urinary albumin excretion 5. Since adult mammals exhibit a limited capacity for nephron regeneration, it has not been observed that kidney functions are recovered in patients with chronic renal failure 3, 4. The human kidney is comprised of ~750,000–2,000,000 nephrons, which are a critical functional unit in the kidney 1, 2. The matrix provides structural and functional foundations for the development of cell-free scaffolds with a remarkably low risk of immune rejection and cancerization. Furthermore, active blood flow was observed inside the matrix using computed tomography. The expression of renal progenitor markers, including Sall1, Six2, and WT-1, within the matrix supported the induction of nephron regeneration by the matrix. No fibrillogenesis was observed in the matrix nor the matrix-sutured kidney, although this occurred in a PN kidney without the matrix, indicating the structures were newly induced by the matrix. Twenty-eight days after implantation, glomeruli, vessels, and renal tubules, characteristic of nephrons, were histologically observed within the matrix. A porcine kidney-derived extracellular matrix was sutured onto the surface of partial nephrectomy (PN)-treated kidney. We present that an organ-derived extracellular matrix in situ induces nephron regeneration in a preclinical model.
