Renal tissue regeneration and repair pathways

Renal tissue regeneration and repair pathways represent the collective molecular and cellular mechanisms that the kidney employs to restore its structural integrity and physiological function after injury (NIH, 2017). These pathways are primarily activated in response to acute kidney injury (AKI) and involve the dedifferentiation, migration, and proliferation of surviving tubular epithelial cells, often driven by developmental signaling cascades such as Wnt/beta-catenin, Notch, and Hedgehog (ScienceDaily, 2010; NIH, 2024). Key growth factors, including Hepatocyte Growth Factor (HGF) and Bone Morphogenetic Protein 7 (BMP-7), play critical roles in promoting cell survival and functional recovery (ResearchGate, 2015). While the kidney has a significant capacity for endogenous repair, severe or repetitive injury can lead to maladaptive repair processes characterized by chronic inflammation and the development of renal fibrosis (TechnologyNetworks, 2025). Therapeutic interventions in this area focus on augmenting these natural regenerative pathways or inhibiting the transition to fibrosis to prevent the progression to chronic kidney disease (CKD) (ShebaOnline, 2024). Experimental therapies such as HGF mimetics (e.g., ANG-3777) and BMP-7 mimetics (e.g., THR-184) have been investigated to stimulate these pathways and improve clinical outcomes in patients with renal impairment (NIH, 2021).
