The increase in the incidence of chronic kidney diseases that progress to end-stage renal disease has become a significant health problem worldwide. While dialysis can maintain and prolong survival, the only definitive treatment that can restore renal function is transplantation. Unfortunately, many of these patients die waiting for transplantable kidneys due to the severe shortage of donor organs. Tissue engineering and regenerative medicine approaches have been applied in recent years to develop viable therapies that could provide solutions to these patients. Cell-based and cell-free approaches have been proposed to address the challenges associated with chronic kidney diseases. Strategies and progress toward developing alternative therapeutic options will be reviewed.
