Renal tubule epithelial cells can regenerate in response to acute injury. Although this process remains poorly understood, it appears to involve the reactivation of pathways that are operative during embryonic kidney formation. A better understanding of renal regeneration may lead to the development of new therapies that can attenuate acute kidney injury or expedite recovery. The zebrafish is being used as a model to understand renal regeneration. In this review, we summarize the current knowledge on zebrafish kidney formation, describe methods for inducing acute injury, and focus on the unique capacity of the zebrafish adult kidney to undergo de novo nephron formation in response to damage.
