The nephron, the functional unit of the kidney, is responsible for filtration, reabsorption, and secretion, critical processes for maintaining systemic homeostasis. Damage to nephrons due to pathological conditions such as diabetic nephropathy, glomerulonephritis, and ischemic acute kidney injury can lead to irreversible renal dysfunction and progression to end-stage renal disease. Although current therapeutic options such as dialysis and kidney transplantation have alleviated the symptoms of renal failure, there is no curative treatment to restore native nephron function. Recent advances in regenerative medicine, particularly through the use of embryonic stem cells (ESCs), have shown promising potential in nephron repair. ESCs, due to their pluripotency, possess the ability to differentiate into various renal cell types, including podocytes, proximal tubular cells, and renal endothelial cells, all of which are vital components for nephron regeneration. Studies have demonstrated that renal progenitor cells derived from embryonic stem cells are capable of integrating into injured nephron structures, facilitating tissue repair, and contributing to the partial recovery of renal function in various experimental models. Nevertheless, significant obstacles remain, including immune compatibility, the refinement of differentiation techniques, and the assurance of long-term stability and functionality of regenerated nephron units. This review critically examines recent progress in ESC-mediated nephron regeneration, focusing on the molecular mechanisms that regulate nephron lineage commitment, advancements achieved in both experimental and translational studies, and the emerging therapeutic prospects for chronic kidney disease. The continued exploration of ESC-based therapies for nephron regeneration holds transformative potential for the future of nephrology, offering a novel approach to restoring renal function in patients with nephron loss.
