102) Rainbow trout, Oncorhynchus mykiss
Rainbow trout are native to North America but have been introduced to every other continent besides Antarctica (ÒRainbow-Trout-or-SteelheadÓ). Rainbow trout have the ability of regenerating their kidney if it were to get damaged.
Soon after the rainbow trout has kidney damage macrophages will converge on the injured site and phagocytize the dead cells and other debris. After this stage the kidney will start producing signals that will help the kidney regenerate. The signals are myc, Pax-2, and insulin-like growth factor-1 (Reimschuessel). These signals help initiate the epithelial cells to migrate and start proliferating at the injured section. The cells are used to repopulate the basophilic epithelial basement membrane (Reimschuessel). Then the fish will undergo a nephron neogenesis phase to reestablish the nephrons in the newly regenerated section. The basophilic epithelium cells are used to form the renal vesicles, S-shaped tubules, and tubular outgrowths which fuse with the collecting ducts (Reimschuessel). The BowmanÕs capsule is also made by using the epithelial cells and parts. Once all of the structures for the kidney have been formed the cells will disperse away from the previously injured section and stop proliferating.
